I'm officially giving up on the vertical antenna scheme. I like being heard most of the time, not occasionally. I'll worry about the lightning issue come spring. Fortunately, I already have lots of good wire on hand.

Time to build another inverted L.

I been using this strange setup for a while on the 40-10. Strange Being so close to the ground it actually works ok. Using the 1,000 acre bob wire radial system.

Phil,

I haven't been following your posts about the vertical trials and tribulations, but yours are typical results.  I feel your pain... Wink

For "local" east coast work on 75M and 40M, it is hard to beat a dipole at 1/4 wave high. (even a shorty dipole)    

If you do go with the inverted L, be sure it is way in the clear, away from buildings, towers, power lines, etc.   (To reduce both pattern distortion/absorption and RFI)     A horizontal dipole is more immune to these objects due to its higher take-off angle and horizontal polarization.  It is less Earth ground dependent too. The higher takeoff angle is also better suited to closer in AMer population concentration on the east coast.

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed.  Easily done in DSP.

I can only take so much frustration and then I get pi**y. Just ask K4SMN.

I have been using an 80 meter horizontal loop for years, seems to work well and is pretty carefree.  Also easily used on higher bands with a tuner.  My 18HT mostly gets used for contests.

I almost hate to bring this up, but an inverted-L is essentially a top loaded vertical. Grin

Yep, 150' long. I've always had good luck with these. Just got it on the air with only time to lay out two (2) radials...playing very well.

It's really hard to get a 36' foot vertical to play well without lots of extra widgets.
