Suppose you were planning out your first HF rig. What antenna or antennas would you go with to start? I am free of covenants, and I have some space in my yard, but I also have small children and dogs who play there and a spouse to contend with. I am a complete newb to HF. My interest is primarily in emergency coms, but that means I need to learn how to operate on HF by making contacts, participating in nets, etc. I can probably rig up a dipole or two, in the trees, but I don't think I can do one for each band. That raises the question of which bands I should focus on. Is 20 meters the place to start?
Please school me on this. |

There are multiband wire antennas, G5RV, off center fed dipoles for a start. If you can do it get a rotatable beam antenna for as many bands as you can afford, and wire antennas for whats left.
|
|
[#2]
If you're confined for space, or looking at a slim budget, a G5RV or OCF dipole can cover several bands and not take up huge amounts of territory.
|

[#4]
What type of transceiver you plan to start with? Internal tuner, power output, USB interface for computer digital modes, etc. Then I could better answer. You could put up a simple dipole with 20 & 40m elements & feed in the middle. A 2 leg fan dipole I guess some may say. You could then work 15m, 20m, & 40m quite easily with any rigs internal tuner. That would keep you busy a long while on HF.

Budget and MS Paint of your lot with rough dimensions please. View Quote The one thing I will say, based on my bad initial experiences with HF, if it can be avoided: 1) don't do a low wire antenna (dipole or otherwise.) Low = less than 1/4 WL above ground. 2) Don't do any antennas in or on a structure with a lot of metal wiring or ductwork (e.g. don't put a dipole 4' above the roof of house.) My being a fan of simple verticals is no secret here, but I think the key is to do the best you can with what you have to work with (land and budget wise.) |

Myantennas.com 80-10 meter end fed is what I would be looking at. Hey, wait... That was my first antenna and I worked all 50 states and a crap ton of DX on it. It's a little spendy but it's a great antenna that can lay across the top of a tree or two. The feed point should be at least 10' of the ground but it makes it very easy to mount to the side of your house which also makes it easy to get your coax ran. You will still need a tuner. I still use mine for 80 and 40 meters. I use my hex beam for 20-6 meters.
Just my $0.02... |

If you have room (& even better - some trees), a open wire fed full wave loop can be a really nice all band option at a really low cost. I have both 80m & a 160m FWL's fed with home brew 4" open wire "ladder line", everything made with 14 AWG THHN wire from Lowe's & some electric fence insulators from Tractor Supply. Although I have other antennas (and had various others in the past), the loops get the most use. Google "skywire" for some details...

Most of the nets are on 75, 40, and 20 Meters. If you're space limited, 40 and 20 Meters would be your best bet. A fan dipole would work nicely.

The verticals already mentioned, with a good tuner at the base, are great choices, as long as you put down sufficient radials.
Another great set of choices for an all-band antenna, if you again have a good tuner, are these dipoles. Get a good 4:1 balun from DX Engineering and a wide range tuner, something like an MFJ-993, 994 or 998, depending on the power level. |

Currently, I have the following:
- Homebrew OCFD with a Balun designs balun - Homebrew ZS6BKW (which is a modified G5RV) - Chameleon EMCOMM-II end-fed half wave in my go-bag - Comet UHV-6 on top of the Jeep An OCFD is easy to make but it needs to be up and the coax up to the feed point can get heavy. The ZS6BKW works OK, I've hit Russia, Europe, South America, and California with it. Mine's hoisted up on a Harbor Freight flagpole about 20ft. Not great but it works for what I need it to do. Just got the EMCOMM-II this past weekend and made a contact in Spain on PSK-31. If I get sent to PR or USVI, I'm taking this is it's the most compact. The UHV-6 is a great mobile antenna. Doesn't have as good a performance as something like a Tarheel screwdriver, but I can still reach about 2000mi on a good day on 40m. And, it works great for 2m and 440Mhz with my FT-857D. I'm still a newb with this stuff since I got my General just last April. Seeing some of the verticals in the posts above, I may give them another look. YL doesn't like wires all over the back yard. |

Any antenna is better than no antenna. Repeat that about 5 times in your head. You can prob make a antenna for next to nothing if you have access to a antenna analyzer. The 43 ft vertical is hard to beat for dx. If i could pick a antenna now I would say a Hex beam, g5rv, or a 43ft vertical. Remember the vertical needs radials.. Prob 12x 32 foot radials... My first antenna was a 18ft vertical which worked very well, with access to a analyzer you can have a antenna that is resonant and will not need any tuning..

It's hard to give advice without knowing all the details.
One thing I can tell you is that it's hard to beat a simple dipole antenna. It's relatively easy and cheap to build and to install, providing you have tall trees and sufficient space. Perhaps look at building a "fan" dipole that will cover 80, 40 and 20 meter bands. These are the bands you will find most activity on at this time of the current solar cycle. |

my first antenna was 103'+/- of 14ga wire hanging about 8' off the ground connected to a LDG 4:1 Balun on one side, with the other to a ground rod and then a counterpoise laid on top of the ground.
That was what I used when I got my General and was hot to make HF contacts, and I did! |

We're limited on space, so I went with a G5RV and an antenna tuner.
I've been able to work every band, 80m to 10m, with no problems. |

I've moved a lot over the last few years, and while I've had space to put up some nice dipoles, I've opted for the simplicity of end fed antennas. It keeps the entire process super simple and keep the numbers of supports, wires, and marital strife to a minimum. I have used 4 or 5 of the LNR Precision End Fedz over the years and they work really well for my applications. Just my $0.02

1) don't do a low wire antenna (dipole or otherwise.) Low = less than 1/4 WL above ground. View Quote do what you can and play radio. Antennas... if you only have one band, make it a 40 m dipole. That band works most of the day and well into the evening. 75/80 m does not begin to propagate until just after sundown. 20 m, 17 m, 15 m shut down about sundown, daytime only bands. So, if only one band, make it 40 meters. An excellent antenna that would get the most bang for your buck would be a fan dipole with 40 m and 20 m elements, allowing you to also work 15 m and 17 m with your tuner. An OCFD (aka "Windom" - sic) with a 38% feedpoint, overall span of 66', will work the same bands. With a 33.3% feedpoint you can work 40, 20, 17, but not 15 m. A 3 element fan dipole, for 75, 40, 20 m will let you work 80/75, 40, 20, 17, 15 m, and possibly 10 m. |

Not sure if you guys are aware, but the 450d internal tuner is next to useless. You have to be below 3:1, closer to 2:1 SWR for it to work.
I dipole for a specific band is great, but you'll soon get tired of your friends talking about their latest contact on -insert band you don't have- |

I am trying to get into HF on a reasonable budget. HRO has the FT-450D for $679. That seems to be about the entry-level cost for a modern HF transceiver. I can expand my antenna setup later as funds allow. The highest I can reasonably get the antenna is about 40'.

A height of 40' isn't that high but its not terrible either. Figure you want 33' for 20 meters (1/2 WL), and ideally 66' (1/2 WL) for 40m.

I love my 450d, but any of the lower price range hf rigs internal tuners arn't that hot.

If you have trees and need to hide it the standard G5RV really is a decent antenna if you just want to get on the air.
I started with one and a FT-840 and an older MFJ manual tuner...$600 total. But then I found digi modes, and while I could do them via an easy-digi interface on the 840, the filtering was making life tough. I upgraded to an IC-7200 and loved it for years. I would get a radio with a real soundcard interface unless you are vehemently anti-PC. Careful with the smaller auto-tuners, as they have power limitations for the digital modes. I have had 3 different homebrewed antennas in the yard since then and am currently running the same ole G5RV dropped a bit for NVIS and a big G5RV-MAX-E for primary. Still no antennas on the tower maybe when it gets colder and the leaves are all gone I'll put the beam up. |

My favorite general purpose All-Band DX antenna is the non-resonant Inverted-L. It has low angle radiation on all bands, which is what we want for DX work. The 45 ft version 23 ft tall x 22 ft wide is good for 80 M through 6 M, while the 90 ft version 45 ft tall x 45 ft wide is for 160 M through 10 M.
On the lowest bands, gain and polarization are that of a vertical, while on the higher bands, polarization of the useful low angle radiation is horizontal and gain is nearly that of a dipole at the same height.
