I can't run wires on my property( no trees and tower rotates). I've used a ^btv
for years with usual weak results on 80. LAways thought Butternut was weakly made. What is recommendation out there? Butternut Gap Force sigma for 80 know very little about it they don't answer e-mails MFK ??? other ideas Really want 80 and 160 would be great bonus. 73 Gerry |

I know it would be somewhat "unsightly" (beauty is in the eye of the beholder), but an inverted Vee would do pretty well on 75. I had a 75 dipole at one of my prior residences that drooped down to 10' and it worked better than I expected. So if you could droop a V down off the tower (the whole thing doesn't turn does it?) it would work. There are also some ways you can make a loaded vertical to hang under a tree/tower--saw that in QST a few years back. A bit of experimenting, but a good project which, according to the author, got some pretty good results. Sloper off the tower? And then you could put a screwdriver at the top to work all bands and put radials underneath--saw that method, again, in one of the ham rags where a series of wires of different lengths were positioned in a circle like a bird cage with a home- brew vertical at top. Lots of ideas. I don't know how they work (haven't had to try it). If you get out and "putter" with it, you'll come up with something. Now if you need a help with a screwdriver, just let me know (www.qsl.net/k4kwh) . 73 Jerry K4KWH |

Gerry,
Do you have guy wires on your tower? How long are they, and how hard would it be to put an insulator on the top end of one, or several? How about loading the tower? Or running a wire from the top to some point close to the shack, or a tree / pole / top of the garage? All kinds of possibilities. An 80 or 160 meter antenna doesn't have to be of any 'classic' design to work. You may have to use a tuner, but that's no big deal. Guess it is if you don't have one, huh? 'Doc |

Don't know what you mean by weak, my HS5 (mounted on top a 14' base pole,
with a total antenna height of 40'. It is mounted in a surveyors tripod. It has withstood winds up to 75mph with out guying. Works great on all bands (using a simple tuner. Plan on adding on a additional 10 more feet of base, and I the will guy the base pole at 23'. There will be three guys, one affixed to each tripod leg anchor. Butternut makes good tripods, but a lot depends on how the user puts them together. You got to have radials and a good ground. Jim "Fjx1" wrote in message ...

You got me! Instead of HS, it should be HF5. I also should have given the
full model number HF5-Il, which covered 80, 40, 20, 15, and 10-meters. I have added coils, as needed for the for the other bands. Rolled them myself using aluminum fence wire (.25" dia), same diameter that butternut uses. All the aluminum tubing is original. Jim "Fjx1" wrote in message ... You got me. What is an HS5? Not familiar with that model. Tks Gerry --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
