I have two DX Engineering 20DX-6 antennas. Both of them are mounted in the clear, over a wavelength high and have the same poor SWR pattern. They were built using the recommended settings and the low
I received many direct responses. Some suggested modeling the antenna, one volunteered to model it for me, one suggested calling the manufacture (who's out of business), one suggested a bad balun, an
In a machine shop I used to drill 4140 Chrome-Moly with regular High Speed Steel drill bits. This was in a drill press, I know that it's a lot tougher with a hand drill on a tower. I still think a re
My mast is very discolored from a lightning strike two years ago. I've not experienced any corrosion problem. 73, John I took a lightning strike at 3:00 pm local time yesterday. My wife described it
Polyphaser also sells a ground rod clamp and 1 1/2 and 3" copper strap conductor. You should look at their catalog for proper installation of ground rods. The S.S. clamps Steve mentioned are very nic
I spliced a long run of 3/4" CATV hardline once. I soldered the center conductors using a small copper tube as a connector. I then insulated it by using some of the insulation from a small scrap piec
I have owned several Universal Towers. My very first tower was a 30' one and I installed the mast, rotor, and antenna before erecting the tower. It was very hard to tilt the tower into position with
That's pretty heavy for a five element 20. I usually attach the boom struts to a support mounted on the antenna boom. That way you can tie your rope to the center of the boom and to the top of the st
I'm looking for a manual for a Hy-Gain 204BA. Not too long ago you could make a quick telephone call and they'd send a manual for free. I requested a manual using the e-mail address on their web site
My tower was hit by lightning two years ago. The tower has 15 ground rods and the control wires running into the house are protected with Polyphasers. These are mounted on an insulated copper bar in
You can use a heaver wall or larger diameter for increased strength. I just purchased a 56# - 2 1/2" diameter x 1/2 wall x 15' aluminum mast for $250 from http://www.metalexpress.net . John Hi, Steve
I put up a 60' Universal Tower with I believe a 30" base using a tow truck. I had the tow truck raise the boom as high as he could (maybe 15') and connected the cable at around the 25' point of the t

Before painting your tower you should wash it with TSP and rinse it thoroughly. You need to be sure that you purchase paint and primer if necessary that will adhere to the galvanized finish. You prob
I use a hacksaw with two blades installed. John Anyone have any tips for cutting slots in aluminum tubing without having a full machine shop at your disposal ? Thanks, Steve, N2IC ___________________
When you select 1 or 4 antennas the Stackmaster uses the 50 ohms stubs to match the impedance. When you select 2 antennas the Stackmaster uses two 75 ohm stubs for the match and when you select three
OK! I am looking for a 60' or taller Free standing tower located within 3 or so hours from Indianapolis. This will be used for a large TV antenna and possibly an HF antenna. Replies directly please.
I really question this. Why would lightning not strike a well grounded tower. Once, I watched a storm approach my station. As it passed over I saw lightning strike my tallest tower which has 15 groun
Maybe having numerous towers also keeps tornados away : ) Very limited as I bought it and started planting towers right away. As I recall, in the first month before I got anything put up, I put a sma
