So, I've got most everything I need to get my base-station set up, but I'm having a hard time finding a couple things (my power supply is backordered, of course!).

For the life of me, I can't find an antenna cable-connector/outlet to go through the wall of my office/radio shack. I'm sure one is made - like I attach my cable TV to, but for HAM antenna cable . . .

Also, I have a 10' piece of aluminum pipe I'd like to use to get my 2m antenna a little higher (either a ARX-2B OR ARX-220B, from Cushcraft - not sure which).

Anyway, I think I need insulated brackets to connect the two, but I can't find anything like that either. (I'm mounting it to my chimney and using guy-lines tied to cinder blocks to hold it/protect it from wind. I have a flat rubber roof, so that should work pretty well, I'm thinking.)

I'd sure appreciate some help/guidance. Feeling pretty lame/inadequate here . . !

Thanks!

Welcome in!

There are  countless ways to bring cable inside.  How exactly are you looking to make that happen? Drilling a hole? Window sash?

Those antennas you listed are a Single Band 2m antenna and the other is a 220MHz only antenna. What bands are you interested in? What radio do you have to connect to the antenna?

Most Vertical Antennas have an insulated section at the bottom to mount to your mast-not usually a problem!---you may not need to guy?!

You're talking about a finished plate that har as so-239 connector on it like one for tv would have a f fitting on it?

Get a bulkhead so-239 and a blank panel.  Drill, baby, drill.

There are also some pre-made panels what can go under a window.  DX Enginerring or MFJ are likely sources.

Yep. No driver needed! (Thank Goodness!)

The ONLY thing (besides the power supply) I'm missing now seems to be a male-male cable to go from the barrel connector (ordered an 8" from Amazon) to the transceiver itself.

I'm a fan of drilling a 1" hole at a slightly downward angle putting a piece of PVC through the hole. The downward angle keeps water from running in. You can chalk the PVC and pack with foam/stainless steel wool keep bugs out. Cheap, easy and no extra connectors to add loss in the line, especially with UHF.

Well, I got the antenna up yesterday.

Today, the grounding gets done and the drilling for the pass-through barrel-connection into the shack - then, it'll be time to tune/transmit!

*For some reason, I can't figure out/remember how to post pics, so that'll have to wait.

My buddy (who helped out) says I can't have the ground wire laying on the rubber roof, so I do need to figure out how to keep it suspended. I'm thinking about bolting a piece of PVC to the edge metal/facia and feeding the ground wire down, through it. It's not going to look too pretty (sorry, baby!), but it should work well enough.

Oh! Then, I need to do the guy lines too. I don't remember if I'd said, but (without any other options I can think of), I'm going to use paracord attached to cinder blocks. It won't be fun hauling the blocks up the ladder, but it seems the best way to support the mast.

One last thing (for today!) . . . the antenna is a Cushcraft Ringo Ranger II ARX-220B. We followed the installation instructions to the letter and it looks like I'll only be able to use it between 220-225 MHz. Will a tuner allow me to use a broader range of frequencies?

Thanks!

As I posted above, that antenna is built only for the 220 MHz Ham Band. You may be able to hear on different bands with some success but I'd not use it for transmitting.

Are you wanting to talk on 220 MHz?
Do you have a 220 rig?
If not, you're not going to be real happy.
Ringo does make a 2m (144 MHz) antenna and it has a similar product number.

Indeed, if you transmit in 2m or 70cm, at best you'll have a crappy signal, and at worst you'll have high SWR, pushing power back into your radio, potentially damaging it.

It's a 220mhz only antenna. As a just-starting-out amateur it's very unlikely that you'll get much use out of a 220mhz antenna. 220 is a great band but is almost abandoned in large parts of the country other than for some behind-the-scenes things like repeater linking and some digital point-to-point.

A couple parts of the country use 220 more heavily due to restrictions on the 70cm band due to PAVE PAWS radar systems. But you don't really have a 220 radio.

For general amateur FM use in most places I'd suggest either the Tram 1477 or 1480 for a starter dual band vertical.

If you actually need a tri-band antenna (2m/220/440), and/or want super wide coverage for receiving other stuff, 900mhz, or something similar, a discone antenna would be something to consider... unity gain but is a broadband antenna.

You're not going to use an off-frequency antenna with a tuner on VHF/UHF bands.

I looked closely at the instructions and reconfigured the antenna to the height (in specific sections) for 146.000MHz and it seems to be working fine.

That said, I was surprised yesterday when my GF was at home and I was about 5 miles away. I was on my VX-7 and came through to her loud and clear.

She was buried in static on my end, though. With the FT-2900 pushing 75W I would've assumed the reverse.

I'm sure there's something I'm missing. Comms isn't just a plug-n-play exercise, after all!

Just to be clear, you have the FT-2900 using the 220 mhz antenna that is reconfigured for 146 mhz?

if so, your reception of it is a clear indication that the 220 mhz antenna is not working on 2m and is not working fine.

an antenna may work fine on receive but kill the finals on transmit because most of the transmit power is reflected back to the finals due to a bad SWR.

If it were me I would  not transmit with the FT-2900 on that antenna again until you can confirm what the SWR is the transmit frequency or you might kill the radio.

I don't think you can reconfigure the ARX-220B to work on 2 meters to my knowledge.  It sounds like there was some miscommunication with the person who recommended the antenna, what you want is the Cushcraft ARX-2B model for working 2-meters in that product line.  I do see how it could be confusing, however, as Cushcraft has one instruction booklet for both models.

The likely reason your FT-2900 isn't transmitting as well as you'd expect is because you're using an antenna that's way out of tune/resonance for use on 2-meters, and most of the power the radio puts out is radiating back to the radio and cooking the finals, eventually leading to a broken radio.

It can be, it's not when you use the wrong antenna though.

Not sure why this is not communicating that an ARX-220 antenna will not work on 2 meters and could quite possibly damage your radio.

Okay guys. I'm reading you loud and clear.

It's entirely possible the antenna isn't right. I'm looking at the illustration/pictures I can find online and I'm pretty sure it's the 220B. That said, I'm going to call Cushcraft tomorrow to try and determine what it is, once and for all.

If it is, that'll suck because the ONLY other antenna option I have right now is a never-used Buddipole and I don't want that out there in the weather all the time - although, if I'm not mistaken (a very real possibility, granted!), I can use that for everything - even setting it up for my FT-817 to listen to all bands (now checked and confirmed [except for 70c]).

That said, the configurations change to do that - making that not a great "permanent" option anyway. Of course, I can always set it up for monitoring higher bands if things go sideways.

If I were to drop something like $150-$200 on a new antenna, is there one in particular you guys would recommend (for 2m in particular, as I understand the 2900 excels at that - and that's what my ham buddies have)? I sure don't want to screw up my radio - and not transmitting properly kinda makes even having a base-station a moot point.

Thanks again! You guys are awesome and I really appreciate your wisdom, experience and guidance.

Earlier in the thread I posted....

For general amateur FM use in most places I'd suggest either the Tram 1477 or 1480 for a starter dual band vertical.

"Dual band" generally refers to 2 meters plus 440 / 70cm. It could be two other bands, but unless something is specified or there is some other context it's 2m/70cm.

Either of those Tram antennas are reasonably low cost and should work fine. If you'd happen to be somewhere with a lot of ice & wind loading or other extreme climate it might be best to look at some other alternatives.

Power Supplies, I highly recommend Duracomm equipment.  Built to commercial/public-safety specs, not ham specs.  I've got an LP18 on my desk.
They also have "hoods" you can screw to the power supply itself, then mount the radio in the hood.  Keeps everything together on the desk, neat and clean.

From the antenna on the roof, run the coax straight down to the ground level.  Pound in a ground rod, bolt a polyphaser to it.  Connect coax from antenna to polyphaser.
Inside, get one of those bulkhead connectors and a wallplate.  Mount bulkhead connector to wallplate.  Drill connector-size hole through wall, avoiding any electrical/water/sewer/gas/telecom wiring.  Build a shorty little cable to go from the polyphaser to that bulkhead connector, assemble and secure wallplate+bulkhead inside.  Caulk/paint the cable penetration outside.  ???.  Profit.
Now your shit's grounded and surge-protected outside the house, not inside it.  

Some guys even go so far as to get a little NEMA enclosure or plastic box, mount that to the house, and run grounding/connectors/etc in there.

make your own SlimJim antenna.

It is very easy, but you would need an antenna analyser ( can get an nanoVNA for $50 ) to check it out, which if you are going to play with antennas you should have anyway.

I recently made one for under $5 dollars. Literally some wire and a piece of 1/2 inch PVC fro the frame. I made a thread here about it. If you already have about 80 inches of any wire and a 58 in piece of scrap PVC it will be free to make. If you want to connect it to an SO-239 then you will have to buy that connector for $5.

That doesn't make sense. The ring at the feedpoint is part of the phasing system and is a different size between the two. The coax that goes between the feedpoint and the bottom radials is a tuned length which is band-specific, although a Ringo can be used without that part.

He also suggested I pick up an SWR analyzer as that will confirm whatever the problem is and help me make adjustments. (Better than just an SWR meter, he said.)

Yes when working on antennas an analyzer is orders of magnitude more useful than a power/swr meter.

You get a Nano VNA? The teeny connectors are SMA, you'll need adapters up to BNC or SO239.

I would think it goes inline with the antenna cable . . . No?

Yes. The NanoVNA is what I got.

Oh! And I have some adapters, but I don't know if I have any to fit these tiny ones.

I need to end with PL-259's I think (or, the female version - whatever that's called)  but, I did see there's a small female plug in the back of my FT-2900. I wonder if that's where I plug in the analyzer(?).

No, the Nano VNA doesn't go inline with a radio, you won't use your radio at all.  You need to attach coax straight from the top port on the VNA (S11) that goes right to your antenna.  Make sure the antenna is setup somewhere in the clear and several feet off the ground when measuring.

You'll also need to calibrate the VNA, it should have come with a set of calibration standards.  I highly suggest you watch some videos on how to calibrate and use these, they can be a bit advanced for someone new to analyzing RF gear.  There was a recent thread with a few decent videos on them:  https://www.ar15.com/forums/Outdoors/Live-Presentation-Alan-Wolke-W2AEW-An-Intro-to-NanoVNA-11-13-20-0030-UTC/22-698564/

@SCWolverine Most of the adapters at the linked site are out of stock.

Here are some of the adapters I have. The two in the middle-left are cobbled together and kind of look like the one picture I was able to see on the linked site.

The others...? I don't know. Without pictures, I don't know if I have anything I can use.

@D_Man. Thank you for posting that instructional link. I'm doing my best to take notes and absorb as much as I can!

I have these two cables, also. I don't know why! I also don't know why one is gold and the other silver...

Are they anything I can adapt and use?
