This is the second allusion to 1/8 wave elevated radials that I've read, but I've been unable to find anything further, in the usual sources.  Any leads?  I have an inverted L, but really don't have

Anyone got an innovative way of getting 8-foot ground rods out of the ground? I'm taking down my 160M RX and TX setups for the summer and have one stubborn one.  I've tried the visegrips and even tri

Thanks to everyone who suggested things.  I'm going to try Visegrips and a board under my car's scissors jack tomorrow, and if that doesn't work I'll just cut the ground rod off below the surface.  I

Just as an aside, I was once (too long ago) State Department desk officer for Zambia, during a major slump in copper prices, and saw first-hand the devastating effects on everyone when a country depe

Amen to that - I can't remember the actual trig formula, but I do know that as sag approaches zero, tension on the caternary approaches infinite, rapidly.  Thanks to K1TTT for that insight. 73, Pete

The only thing I know of is K7LXC/N0AX's tribander test which was done a long time ago, like in 1998.  Because of that, many of the antennas in the test have been superseded, and if anyone is masochi

For what it's worth, I had a 2-element Force 12 40M yagi on a 100-foot tower.  That antenna had identical elements, linear-loaded and a hairpin match, and was tough to optimize. What I finally wound

For a number of years while I lived in a townhouse I used an inverted-V fan in the trees behind the house with 10M, 20M and 40M elements.  The 40M elements had W9INN coils near the ends to permit 80-

But like so much of what they sell, pricing is exorbitant.  I doubt there's $3 in materials there.  I'm not naive enough to think that prices depend on costs, but... 73, Pete N4ZR Check out the new R
