Edit3:

6m setup. There's actually one mast leg to go (at the top)

Turns out that 10m comes in just fine lol though no one hears me.





....................


Edit:  since it's so small and light I'm taking the EFHW as well along with its coax. Is there a problem with attaching 3-4ft of paracord to the top, running it under the other antenna and then attaching the end of the EFHW? ( then sloping it down to wherever).

This way to switch to 10-40 I just unplug the 6m coax and plug in the EFHW coax.


Edit2:

Why are you primary set on 6m? I am sure there is a group looking for that grid but 20 and 40 would net you more contacts.

Why not use a vertical? It has a lower take off angle and the saltwater will make a good ground plane.

I think that unless you get really really really really lucky a terrible antenna on 10m will net you exponentially more contacts than an excellent 6m setup.  Just my opinion...

I'd probably be considering a random wire for the HF bands - which would leave the Buddipole free for full-time use as a 6M yagi.

A random wire doesn't require much in the way of support (just about any tree or 2-story building will work), and the tuner in your IC-703 is already pretty close to being able to handle a random wire length - Just add a 4:1 balun at the antenna feedpoint, and you're there.

Earlier this week, I used one of these to put a random wire approx. 40' up into a tree branch:



It worked so well, I think I peed a little.

Skibane - where'd you get that and how accurate are you with it?  I need to get 40 to 50' up into a Walnut tree this year.  I have a slingshot but can barely hit the tree itself with a steel nut tied to a string!

lol.

The EARC is just like that. They designed it with a 9:1 unun.

The mounting options are artificially limited. For sure nothing can be attached to the trees down there and I don't know what else might be available.

Hence the question about attaching to the mast under the antenna structure.


Here are some pics operating from a local park:

I made mine, after a trip to the Wal-Mart sporting goods department - It looks virtually identical to the one in the picture.

You can also buy 'em pre-made (example here), but it's a lot cheaper to cobble together your own.

At short-to-moderate ranges, shooting a lead fishing sinker is almost as accurate as shooting a marble or ball bearing. At long distances, the weight and drag of the fishing line starts to pull the sinker off-course.

Who's gonna know?

Are they chaperoning you or something?

It's not exactly a major construction project:

1. Erect antenna after arrival, and
2. Remove antenna before leaving.

Go to a fishing shop and get a plastic casting plug.

While you're there, get an $8 fishing reel and tape it to a slingshot.

I used it at church to run video cables in the ceiling crawl spaces. Our priest didn't believe it worked, so we shot it down an 80ft hallway at Sunday school and hit the back door. It flies like something out of a Batman movie.

Can you clarify their definition of "attach"? Would a line draped over a branch or tree-top, and then staked to the ground on the other end be a problem? I'm wondering if they mean something like you cannot put nails or screws into the trees.

If you are going to go to all of the trouble and expense, you still may want to consider a backup plan for operating on HF.

6m may be full of fail for you first dxpedition. Have a plan "B" just in case 6m is dead.

Get an 18' S9 vertical and use your rig's internal tuner. The S9 is simple antenna and requires just a few radials to make it happy.

The Buddi-pole tuning seems a bit complicated and from what I have read from your earlier posts is your success with it has been limited.  Keep it simple and your time there may be more enjoyable.
Link Posted: 4/13/2014 9:14:22 AM EDT
Actually running a 6m antenna on the mast, either yagi or vertical is a good idea, as is using the end fed as a HF antenna.
Link Posted: 4/13/2014 9:47:31 AM EDT
What about two MFJ 6m "fiberglass stick" antennas? Put them into dipole configuration.

I have a clothesline reel that I filled with "AFW 1x7 Surfstrand copper trolling wire" It supposedly is 30lb test, and I put about 130 feet onto the coleman clothes reel. I unroll a bit, and put it put it up somewhere, either in a tree, or up the side of my 31' fiberglass jackite pole.

6m Moxon beam could work, fiberglass "snow plow stakes" work well for that, but you ain't gonna find 'em in Florida. Shipping is kinda prohibitive, but you get the idea.

QST May 2014 has an excellent article on building a portable DXpedition antenna. You might want to look at it. If you don't have a subscription, let me know and I'll throw mine in the box I'm sending you.

Have you considered a rope yagi they were all the rage for a while, and died out because they're hard to turn and VERY DANGEROUS. The gain on a 100ft one is about 20dBi, so, consider that into your EIRP calculations. BE CAREFUL IF YOU USE ONE OF THESE. STAY AWAY FROM IT WHEN TRANSMITTING. VERY DANGEROUS. They're very lightweight, and you can probably mark out the ropes ahead of time, and just pack some 1/16" aluminium rod and zip ties. Just keep in mind the MEP controlled and uncontrolled exposures if you use one. It's too easy to cook things with one. (I used one on 70cm and killed some birds and a tree.)

As I think of more, I'll update.

The 15 meter band on up may not be depended on to work.  If you carry only one antenna, a 40 meter wire dipole is pretty effective.  And with a tuner, can work 15 m, too.

But for the same amount of wire, 66' overall, you can make a 40-20-10 m OCFD using a 4:1 current balun, 44' wire on one side, 22' on the other.  Won't do 15 m, no big deal.  But if all you have is 40 and 20 meters you will do very well.  

I just worked a special event on 40 m.  We used just such an antenna hung in the trees (up only about 15' high) for my station.  20 m was dead, the other station said.  I was reeling in contacts, on average, 15 an hour.  This was not contesting, but a lot of chit-chat about the event.

In my conversation with one of the on-site (they have a sat phone system) Rangers they mean, literally, nothing.

But more importantly my proposed setup keeps itself out of the way of people, especially kids who seem to be inordinately drawn to technology and guy wires

My proposal, by special event permit, is to set up on the slab of the North Coaling dock ruins (normally closed) to isolate the setup.

Google Maps view LINK


Plus it provides for an awesome saltwater amplifier into CONUS

I plan on aiming from 20magnetic to 300M.

That's where the other expedition set up also IIRC.

I still say horizontal moxons for whatever bands you want on a 20-30 foot collapsible fiberglass pole.  Run string down from opposing corners to anchor the orientation.

Once camp is set up I'll just strap the GoBox to the ALICE frame (I've already worked it out) along with antenna bag.

Are you bringing a tactical wheelbarrow? Just curious of the logistics of your trip. It seems like a daunting task to get the gear (communication and supplies) to the fort. Forget packing it across what looks like a sand path to the North Coaling Dock.

You edited while I was typing. No food? I figured on 5 gallons of water.

They actually have tactical wheelbarrows at the dock upon arrival.  It'll help get stuff to the campsite.

example:





Things in the pack or strapped onto it are pretty simple for the moment: (mostly in order of importance)

Tent
Fleece sleeping bag liner (basically my sleeping bag)
ground pad
dSLR with two lenses
GoPro and stick
One .mil style canteen (full) with nesting canteen stand/cup
One round style canteen (full) with an aluminum round nesting cup
3-4 slimmed down MREs
Small toiletry kit
Sterno or two
One pair river pants (I'll be wearing the other pair)
One UA long sleeve heat shirt (I'll be wearing another)
One UA compression short (I'll be wearing another)
Bathing suit
Mask and snorkel (boat also provides gear so I'll take their fins)
Oversize baby wipes
Regular towel
Chopped up towel
Soft paint brush (for brushing away sand and stuff off the radio if needed)

other stuff

Have you considered using a telescoping pole?  I use one for my SOTA activations, and have no trouble erecting it in all kinds of terrain.  I use it with either a 20M dipole or a vertical end fed, depending on what I am doing.



From my archive.  I typically send a summit photo for my SOTA QSL's...

I can definitely give detail on the antenna set up.  Today is very busy for me, so I'll take pictures, weigh my antenna bag and get a post up on it tomorrow.  The antenna itself is actually one I made, since no one seemed to make one as light weight as I wanted.  

I've actually been meaning to put together a detailed post for Summits on the Air.  I'll use this as an excuse to break it up into bite sized chunks.

Oh, and let me be the first to welcome you to AR15.com and our Ham forum!
