Tom, this is the reason to have a pull rope attached to the top tower section when using a W-51 or any single-cable ("gravity retraction") design telescoping tower! Tie a strong rope at the top of th

The MW series was *not* self-supporting, nor intended to be. I had an MW-65 for several years, and it needed at least two sets of guys to support just itself in a strong wind, with no antenna load. Y
Lightning ceases over big antenna farms? I sure haven't seen that happen... Biggest lightning damage I've ever seen occurred at WC2K in southern NJ about 19 or so years ago. Rick had big towers, incl

I use NoAlOx (off the shelf, Home Depot and most electrical supply houses) and it seems to last a very long time....used it at all element overlaps and attachments in a KT34XA installed in 1988 and w
The Measurements Corp. model 59 was sold by the tens of thousands back in the 50s and 60s and is very good. I see them surplus all the time in reasonably good and working condx for about $100, and th
Isn't most impedance in a length of copper inductance? The resistive component should be very, very small.....-WB2WIK/6 _______________________________________________ See: http://www.mscomputer.com
I agree with Jim. The traditional "fabricated" pulse used for testing against lightning transients, and used by most industries worldwide, is an 8x20uS pulse, repetitive. This is much closer to RF th

I worked Ivars, KC4PX from Merritt Island, FL Monday evening 9/6. He was operating mobile on 20 meters (or maybe it was 17?), on his way "back home" after the latest hurricane. Ivars is an active con
On this same subject: My old friend Bill K2OWR has a hilltop property that was advantageous to a local commercial 2-way firm, so they approached him about it. He ended up with a 140' self-supporting

Here's one input: At K2OWR's 11 acre hilltop property where we do some HF-DX contesting (five towers, miscellaneous other antennas), there is virtually no "open space," everything is very treed. Bill

What W0UN posted is very true. I've used dozens of ARR GaAsFET preamps over the years, and running 1500W PEP output power on the VHF bands I've never blown a preamp yet. But I sure wouldn't rely on a
What's commonly done with VHF masthead preamps and such, and I've used these for decades, is to simply install electronic sequencing in the shack and use control-line keying (not RF sensed keying). A
The sequencer is not intended for real VOX operation. Normally you'd use the PTT line output from your microphone, or a footswitch which would allow either voice or CW mode operation. If VOX causes y
