Hi: that the Allen a I'm not too have as a You might want to replace the Allen screw with a set bolt, the kind with a square head on it, (heat treated to be a set screw) since this application rotate
Hi: LPS 1 is thin, (like WD-40) LPS 2 is thick, LPS 3 is medium thickness and in a week or two it looks like brown wax, when you dig into it it is like a grease with a slight `skin', look in your cat
You are in luck! First: 33 feet is to long for 7.1 mHz. Second: get Nov. 1999 edition of CQ mag, see page 26, a flagpole antenna made of 2" EMT (aluminum conduit) (designed) 73 (= Best Regards) de:
Hi: You are wright, a jumper is needed. First :Copper braid on Zinc - bad ,a piece of S.S. strap would be better, or a piece of galvanized steel wire would be fine. &: Remember to jab some of that an

Hi:<< For our tower applications, we're looking at resistance to shearing on the bolts. The need to achieve perfect torque values is not so necessary for this sort of application. >> I was taught th
Hi: << I can't imagine that you could squeeze a leg hard enough to create enough friction to take all the downward force, especially on the bottom section of a tall tower. I have to believe the bolts

Hi: I hadn't heard about that, I put 100 feet up in 1973, worked great. Fell apart.(with 100' of Copperweld AWG #14) which I have had up since then as a 40 meter dipole with a current BALUN and RG-11
Hi:<< I'm looking for some imperical data on the lifetime of (Rohn) towers in non-corrosive atmospheres. >> IMHO if you coat the tower and guy wires with Pre-lube 19 from Grenard Co. ??? It will out
Hi: << A 30% tuner loss is huge and would be dissipating 500W of a 1500 watt input in a closed space. That wouldn't take long to set it on fire internally, and would quickly make it too hot to touch.
Hi: << the band switch, which dont tolerate too much current. I burned one out compeletely some years ago, when my antenna configuration made the switch a high current spot. >> My automatic antenna t
Hi: << Anybody out there know of a better solution, or am I overkilling this thing? I have 5 more elements to do, so any labor saving hints would be appreciated. >> I have a KLM KT-34A (not X) and it
I disagree! Quarter wave antennae REQUIRE a counterpoise' to produce an equal but opposite `image' of the elementto be an ANTENNA. Two quarter WL antennae stacked with the feed points together produc
Ground clutter is from buildings and trees, if the bottom of your 40 meter `half wave length vertical' is 40 or 50 ' above the ground, the ground losses become minimal, for instance. I disagree, All
Yepp, try putting a .1 microfarid disk ceramic capacitor across the terminals of the meter movement. (with short leads) 73 (= Best Regards) de: Ron ka4inm@qsl.net VISIT my HAM WEB SITE at: http://ww
Hi: Yes, and . . . A "J pole" antenna is a 1/2 wavelength antenna feed by a 1/4 wavelength stub, total length + 3/4 wavelength. (shorted on one end and open on the other, one side connected to the en
I would consider slitting the thin real cheap PVC water pipe, I would think about 1" size, and white would show up best in the grass. (the stuff they bury to put sprinklers in your yard) 73 (= Best
Hi: It sounds to me , like you have a bad shield connection, you need to inspect and test every PL-259 on every cable in your system. 73 (= Best Regards) de: Ron ka4inm@qsl.net VISIT my HAM WEB SITE
Hi: It is sold as `THERMITE'. Yes, it is being supplanted by specific clamps and compression `fittings' ("lugs" bolted together) for each type of connection condition. 73 (= Best Regards) de: Ron ka4
