People who likes to spend money buys Comtek boxes. People who doesn´t makes a W7EL phaseing unit by themself, not only will they save money but at the same time they will get a better working 4
Jim, With all due respect, some people <have to> spend money on industrial products because they <don't have> enough time for homebrew, but at the same time they want to improve their stations. I ass
I use a variable phasing network for my 2 4BTV verticals that I use on 40 and 20 meters. The phasing unit consists of a roller inductor in series with one antenna and a 500pf variable in series with

1) different principles: the Comtek box use hybrids to achieve +90/0/-90 degrees of phasing, whereas WX0B use a lumped elements network 2) price: WX0B is abt. 3x more expensive Array Solutions argues
Well, I understand this with time etc etc. In this case I merely wanted to point out that Comtek isn´t the only game in town. Also the Comtec box doesn´t do the phasing 100% correct on a
If I homebrewed everything, I'd have 20% of the station I do now. I'd love to homebrew much more, but often its a practical question of time!At 08:34 AM 11/18/2004, Yo3ctk wrote: Jim, With all due re
Yes, I forgot about the WX0B box. I now will rephrase my statement like this: People with a lot of money will buy the WX0B box, uses the W7EL current forcing method, which is a good method. People wi
Now that I'm retired I have the time and a little more room to homebrew antennas and other gear. 45 Years ago, I homebrewed a lot as a teenager because I couldn't afford to do otherwise, and I still
I absolutely agree with Ted. I design and build the things I WANT or HAVE to homebrew. I pick and choose what I'm going to homebrew. I figure the time I spent homebrewing stuff instead of buying stuf
OM Jim, Thanks for stirring the pot. My e mail has been rather empty until you raised this issue. I commend Jay and Array Solutions for their 4 square box. IT WORKIE WORKIE and WX0B provides super su
Actually, there is enough information in ON4UN's book for a competent individual to build a hybrid style (quadrature) phasing unit without much more than an MFJ-259B. Of course a good scope and curr

Don't be ashamed of buying stuff, people. I just paid $65 for a tuning pulser. I haven't taken the cover off, but odds are that its nothing more than a relaxation oscillator and a rotary switch (to c
Actually Joe, I've not only got a good scope and an MFJ-259 and an MFJ-269, but an HP vector voltmeter, HP signal generators, square law detectors, bridges, etc. also. The "tons of time" includes cha
