Topic Author Posted On another confirmation process K4WY on 2/3/17
If you wish to try this service, I hope you have better success than I do.

There are no instructions to speak of, the process does not appear to be intuitive, and there are very few users. I have several matched QSLs there, yet no confirmations. I am at a complete loss as to why this is so.

Good luck confirming V43.
Attic Antennas apr1350 on 23/7/16
Without a ton of loading, a wire that fits into the typical attic won't do much on top band, and, agressively loaded, the 2:1 SWR bandwidth will be painfully narrow, and most radiation would be near-vertical. Those who say it won't work might be right -- about 160m. I hope that's not a deal-breaker for you!

Simple wire antennas often pleasantly surprise me. If you can make more than one excursion to the attic, how about hanging a simple dipole for 14MHz as a test? 33 feet, from end to end, with a SO-239 in the middle. Try an A/B comparison with the vertical, keeping in mind that lately there has been a lot of QSB on 20m. This can at least tell you if there's enough metal flashing, chimneys, etc., to keep your signal from getting out.

For anyone interested I received the plague 6/01/15 from UPS.

I wish you a speedy and complete recovery, OM!
Flash player Making site unusable KBurton on 27/5/16
Flash has security holes and is basically an end-of-life product. PDF and DJVU are good formats for e-mag versions of print magazines and today are trivial to generate.
G5RV Antenna Question N5ERV on 25/5/16
Mounting it 80 feet high should provide you with good DX performance on 80m, and very good to excellent DX performance on higher bands.

You should have very good performance on 20m if you mount it as an inverted V with the apex 30 feet above ground, particularly if you get the ends at least 10 feet up. It's intended to be used as a flat-top doublet on 14Mhz, so you may need use a tuner if you're not comfortable with adjusting the length of the stub. But to use it on other bands, you'd want to use a tuner, anyway.

On 40m the apex would still be almost a quarter wavelength up, so it should still work reasonably well on 7MHz. On 80m, the antenna will be short (large capacitive component with low radiation resistance) and low (making it something of a cloud-warmer), but with a tuner you should be able to work local contacts. It probably won't be sufficient to get you your 80m endorsement for WAS, but you should still be able to work contacts on 80m (and you can expect to do much better on the higher bands).

Good luck!
