Sorry Jim, but just not so. Krause in volumn 1 specifically proved that the maximum gain which could be obtained from an antenna ( he used a simple yagi for his discussion ) is at that point where t

Tom, I hope you will look at that sentence again. This thread is getting to the point where we're misleading a lot of people. There is no such thing as Antenna VSWR. There is something called VSWR an
I would say no. It doesn't take many trips up and down the feedline before the feedline loss will attenuate the thing to a value which is for all practical purposes, non existant. And at something li
First of all Grian, don't assume anything. 3/4" hardline is big enough for you to measure the od of the inner conductor, and the id of the shield. Then get out your handbook and plug the figures into
Hi Lee, just a couple of things. First, in describing your "coil", I hope you haven't just bundled a fed turns together. It actually needs to be in the form of an actual coil. Secondly, it's been 30+
Sorry guys, once the rotor starts to move, the cap is no longer needed. It's job is to balance out the inductive reactance of the motor coil windings, during start. After the motor is running, it's n
Well, Greg, assuming your diagnosis of the bearing being messed up is correct, all you have to do is read this old saying. "If you don't have time to do it right the first time, do you have time to d
No I didn't write that. I use a Musk Ox walking in a circle to turn mine. Anything more complicated is beyond me. 73 Ed -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towert
Well, I've got to be one of the worst in the world at this. PL-259s whimper when I pick them up. But one thing which has improved my work is a Dremel tool with a carbide blade on it. Believe me, when
Mike, of course you can do it by using coax with the outer shield removed. However, you remove the outer shield completely! Make yourself a small aluminum L bracket and mount an SO 239 in it and then
For what it's worth, K4MZW here in town painted his tower black. We're still trying to find it. 73 Ed -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com
Good advice. I seem to remember a rule of thumb which said 10 times the frequency in meters will allow a safety factor in gamma caps. 73 Ed -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html

Well, on the subject of lightning rods, A G7 2 meter antenna is the best I've ever seen. That sucker attracts lightning. Just feed it with hardline, strap it to the tower, and forget about it... I've
Could not agree more with K1VR's remarks. Linda is a ham ( extra ), her dad's a ham, and on the occasions I've asked for parts...they've been sent out pronto. She seems to always take the extra step
Sure, will work fine. But you don't need to put all the stress on the tower. Attach your line ( cable ) at the midpoint of the tower, SECURE the bottom and do a little lift..( after taking the bolts
In the first place, static wicks were developed to bleed any charge developing, not to prevent it. An improper path to ground OR the absense of an area of lower potential renders them useless. Not i
