One small hitch (pun noted), they need to be destroyed before you can haul them away. http://www.govliquidation.com/auction/view?id=6478940 <http://www.govliquidation.com/auction/view?id=6478940&tid=
Here is clarification on the lot vs. item issue: Question: -- Event 9067 lot number 3900 says "Quantity in lot: 198000". When I bid, am I bidding on 198000 items each, or on the entire weight of 1980
Relative to the RFI issue, I have a comment. On my rural property, I had no access to any Internet connection other than the poor performance satellite services. I found a small (four persons from wh
I have many AB-621G portable tower kits I purchased government surplus which I tried to sell a few years ago for scrap aluminum prices. Understandably, no one wanted to foot the shipping. They extend
The government finally decided to sell a useful tower rather than scrap it. Check it out here: http://www.govliquidation.com/auction/view?auctionId=7852760 <http://www.govliquidation.com/auction/view
I'm in Northern California, north of San Francisco, and am looking for a worker or two who are not afraid of heights. My need is immediate, and I'm not after a volunteer - I'll pay! Thanks for any su

After completing my 6.6 kW solar plant, and being initially bitterly disappointed with the HF noise it generated, is to recommend only the use of equipment that has an FCC Part 15 B rating. Also, if
I have 11 or 12 of these mast kits. The 8' piece is the elevator, and I can man handle it pretty easily. The heaviest of the three pieces is a case of the tubes, which I can maneuver around without e
I have assembled my 19 element LPDA with the front 12 elements about 3 feet off the ground and parallel to the ground. The back elements are laying on the ground, but electrically connected in the us
If I were to get the nose to point up higher, maybe 45 degrees, wouldn't I expect the VSWR to straighten out in the higher frequencies? As I understand the LPDA, as the frequency increases, the short
Well, okay, I'm convinced, thanks to everyone's advice, that I cannot expect a VSWR sweep to yield anything meaningful with the antenna on the ground. So I've done everything I can on the ground to e
This is really helpful. When I did the plot with the antenna on the ground, all the dips below 5:1 VSWR were below 10 MHz. Then, after 10 MHz, the VSWR saturated at the graph limits of 5:1. The compl
The boom is actually a structural truss, not involved with feeding the dipole elements. All the dipole elements are fed from a linearly tapered coaxial transmission line transformer, the details of w

I e-mailed with VE6FI some time ago after searching to see who else may have one of these antenna systems. He mentioned that they had to add a friction break at the twin tower base to keep the antenn
Its part of the military AS-3515/GRC system which comes with 2 side-by-side towers, with the mast going up from the ground between the towers. The rotor which sits in a saddle between the towers supp
When the shear pin on my LPDA breaks in high wind, and thus can freewheel, it likes the back end to the wind. Kind-of surprised me, but that's what it does... -Doug W6DSR Which is why you want the an
My commercial LPDA uses guy lengths of 8', 10', 10', 10', then 70' or so of remaining guy to the guy anchors measuring from the tower top. I think the first 8' was determined by the Big Grips' length
Here's another off-topic opinion piece - My equipment is homemade, some at the component level, some at the board level, and some at the module level. I have finished the receive side, and am working
