I've heard that the quality of the Andrew line has diminished in the past few years; the copper outer shield is thinner and less robust making it harder to work with. The industry has been moving to
<RF Parts did not provide any information about themselves on their website, did not provide a sales/service phone number to talk with someone and accepted payment ONLY VIA PAYPAL.> That is incorrect
You really need to slow down and look more carefully at their webpages. The street address and phone numbers are at the top of the main page, www.rfparts.com: 1-800-RFPARTS (1-800-737-2787) 1-760 744
Don't be embarrassed; everyone does things like this including people with good eyesight and websites are often poorly designed. 73 Rob K5UJ _______________________________________________ __________
First thing I'd try is a pair of binoculars. You need light, but you don't need stadium level lighting if you can see detail with good binoculars. there must be some reason why this hasn't been sugge

Gripe all you want but you've used a few examples to try to refute a generalization that has basis in fact. There are far too many cases of poor products from outside US and Europe, not just China,
Disagree. Here's why: There are advantages to LDF4-50 etc. regardless of the frequency and run length. That feedline is robust in the physical sense. It can be installed and you are probably good wi
I never fail to be amazed at the people who respond to terse incomplete sentences sent as texts from smartphones, with no signature, no call sign, almost no helpful information. "The neighborhood com
Great switch. If there's any kind of failure mode on this it is probably the splines that accept the male center pin eventually losing their grip but I have not seen that happen, so this is just spec
What's wrong with the good old ceramic dog bone center insulator? But forget the 160 m. vertical dipole; I want to know how you're going to ship and put up the 260 foot tower to hold it. 73 Rob K5UJ
I have a few problems with this wire. My experience with aluminum is that it is not worth the trouble integrating it into the rest of the antenna system when it comes to bonding it to other metals. I
Last year I purchased an Airspy HF+ Discovery SD receiver. Eventually I got around to trying to use it with a second hand Windows laptop. I was concerned about blowing out the front end on transmit b

I tried that and it did attenuate the signal but not by much. Not enough for the kind of isolation I wanted. 73 Rob K5UJ _______________________________________________ ______________________________
Whatever you wind up with, make sure the UHF jacks (if it uses them) on the enclosure are decent Amphenol jacks. I purchased a very high quality filter a number of years ago, from Clifton Labs and th
Not if you use enough radials. I don't think I've ever seen ferrite cores out on heliax at AM broadcast towers. If you use enough radials, the return current will be so divided down that the current
Thanks. I forgot to mention that it is helpful to have your matching network at the feedpoint. However, I currently tune my inverted L on 1880 with an in-shack L network. With 101 radials I don't fi
I've never owned a tower but I would think the guy anchors need to be set in a relatively deep hole that is filled with concrete. I don't think I have ever seen a commercial tower that didn't have gu
It's ridiculous to draw an equivalence between a lattice tower properly resting on a pier and pin with a telephone pole, that is solid wood, and in the ground 10 feet in a tight hole made with an au
