Portable HF antenna

[Mashurst]

I just picked up a TS-450SAT and I'm looking forward to using it out in the mountains. I need to work on my antenna setup next.
I'm thinking something that can be tuned on 10m-80m with the 3to1 tuner in the 450, can be set up in less than maybe 15 min by one person and will have good efficiency to give me a fighting chance at working a bit of DX on 100w SSB. I like the idea of making my own but I'm willing to look at commercials as well.
Anyone have a setup they like?... G5RV, inverted V, slopper, windom, a loaded vertical? What about the Buddy pole/Buddy stick? or that H shaped one?

Since your looking at 100watts I assume your not talking a man portable station. a simple dipole hung over a tree would work fine. Unless your building your own, skip any g5rv or windoms since almost no one makes a real one. Make yourself a couple of dipoles 80/40 with a aligator clip to jump between bands.
Similar one for 20/10m..

I use a Buddipole with my TS-480SAT and like it real well. It fits all your criteria, though you would need a different coil for 80 Meters. It's like an Erector Set or the Tinkertoys of portable antennas, you can build whatever you want/need on the spot. It's not cheap, but it is a pretty complete solution that can be carried all in one small bag about the size of a small-ish tent bag. I've used mine on 10, 12, 17, 20, and 40 Meters so far. I've tried several different dipole configurations but have found that for me a simple vertical with a single wire counterpoise works the best for DX. I have made SSB phone contacts all over the world with 100 watts through mine. There is an excellent support group in the form of a Yahoo Groups mailing list also.

45-degree dipole at my home QTH:

I don't have any current photos of the single vertical that I'm using now but it is super simple to set up and tune.

Have you thought of a NVIS antenna? Here are a couple of links to make your own NVIS antenna.

Aren't NVIS antennas designed for regional contacts less than 500-600 miles? No experience with them personally; just asking.

Just putting out an option.

Thanks for all the input guys

The thing tips the scale at something like 16 lbs so I hope I never have to hand carry it very far.

This is sage advise I'm sure. A simple dipole is hard to beat for value. Do you have a favorite method of getting your lines up in trees? A launcher of some kind? or just a weight on the end of a string?

Unless your building your own, skip any g5rv or windoms since almost no one makes a real one.

What do you mean here? What constitutes a "real one"? I would be almost certainly be building my own. Are you saying the commercial ones deviate from some canonized design? If so the next question would be why and do they work better in some way?

I use a Buddipole with my TS-480SAT and like it real well. I don't have any current photos of the single vertical that I'm using now but it is super simple to set up and tune.

I have a friend with one and I used it a bit once. They do seem to have versatility nailed but I wonder with all the different configurations and all of them being so close to the ground if it's more show than function. If you have settled on the vertical configuration, do you still figure the rest of the stuff is worth while? Are you running both sides in the vertical configuration or have you gone to just a setup that is basically just the buddy stick?

Your blue FJC looks like Schlumberger :-) My wife's FJC does too.

Back on topic, a G5RV works well for me. An off-the-shelf antenna is not unreasonable, or you can make one yourself for cheap. I was out camping this weekend and put a G5RV between a couple of trees. Using an LDG Z-11 Pro auto tuner for convenience I worked many stations on all the HF bands, including 60m. Contacts were made all over the USA and also Quebec, England, Isle of Malta, Barbados, Venezuela, Germany, Slovenia, Finland, France, and Cuba. That was with 30W with a PRC-320 (British Clansman backpack transceiver) and battery.

IMHO the longer wire antennas will far outperform a short loaded antenna. Simple wire antennas work great if you have a few minutes to string one up.

All I can say is that I've logged QSO's to Japan, Norway, Ireland, Greece, Central and South America and some others I don't remember with mine, all with 100 Watts or less. Most of them in less-than-ideal conditions, i.e. close to the 15' high metal building my shack is in.

What I use most is definitely more like a Buddistick than a Buddipole. I use only one set of arms, whips and a coil (if need be), and just a simple 1/4-wavelength wire counterpoise for the other half of the dipole. It's quicker to set up and take down, easier to tune (by just rolling or un-rolling some of the wire), and works great for DX contacts. Not sure if the Buddistick comes with the tripod and mast or not though, and I do use those. There are some extra accessories worth having that I bought too, like longer arms and longer whips, so you don't even need a coil on the lower bands. And the Rotating Arm Kit.

If I was buying it all over again, I might just buy the Buddistick and then add the accessories I wanted.

Preferably I like to use full-sized dipoles or a 20/40 loaded dipole that I purchased recently. But, I can only hang these with some help unless there are some well-placed trees in the area. In forested areas without well-placed or approprite height trees, and with persons to help...I do this:

It's a Max-Gain 50' heavy duty telescoping mast. I also have a second one cut back to 40'. They both work great for getting dipoles to their optimal height.
With trees and without help, I use a a modified "wrist-rocket" style slingshot with an attached Zebco 33 casting reel to launch a line into the trees. I made mine, but there are commercially available slingshot style launchers that can be purchased.

In the deserts, again with help, I use the Max-Gain masts. Without help, I use something entirely different. I had considered the BuddiPole but wasn't convinced I could get them high enough to function properly in the desert. The mast system they provide is nowhere near adequate for anything below 10m.
So, I hunted around for different portables and found this. It met my criteria with one point being that I could deploy it in crappy conditions (gloves or numb fingers and dogs blowing off their chains), and do it quickly.

Technically it's a capacity-hatted vertical dipole, and they have been mfr'd for use on dxpeditions for years by several makers. They are quick to deploy and like being near the ground. They come with a few operational caveats like most any antenna...but, once understood, they work great. I've turned a few offroaders onto this setup and they seem just as pleased.
