Shoot...connecton was refused on this link....also the K4XS link was over the size limit. Gee, I never get to see anything, guess I did miss something, life is hard sometimes! 73 Jim SM2EKM -- Blake
RG217 is good for rotor loops, rated about 1000W at 144 MHz, much much more on HF. You can get both N and DIN 7/16 connectors for it, PL259 (solder type) connectors can also be fitted. 73 Jim SM2EKM
Why not build one yourself? It´s not difficult and you will be able to get something better then what you can buy. Seems like nobody even consider anything but buying in America these days. 73

Why not use RG-217 for rotor loop, excelent cable. To seal connectors just use vulcanising rubber and electric tape. First tape then the rubber then another layer tape, will last forever. Very very b
This is correct however you can also use a signal generator (or even your TX) and a voltmeter with an RF probe. 73 Jim SM2EKM -- Chuck O'Neal wrote: At 20M, getting them within a foot of each other w
Forget about washers or tread lock stuff. Properly done the bolts/nuts should be installed to the correct torque using a torquewrench. A good idéa is to use ordinary flat washers out of very h
This brings back old memories. Back in 1970 I had a tower exactly like this, was 65 feet tall and worked great. Very easy and cheap to weld together, me and my dad made it out of scrap we picked up a
It was Bill Brown W0SYK, the big signal! I Remember the article but not in what magazine. 73 Jim SM2EKM -- Terry wrote: Can anyone come up with the magazine and issue that featured the home brew Big
Who will care? 73 magazine is no more, W0SYK is SK and also W2NSD SK (I think). If I had a web page I would have put it up. 73 SM2EKM -- daniel hearn wrote: It has been bro;ught to my attention that

It depends on the type of concrete. You must ask the concrete company what the cureing time is for the specific concrete you did buy. That´s how it works in Sweden and I´m sure it´s
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
The 930 S-meter is quite logaritmic. Around S-2 it´s close to 1 dB and S-8 to S-9 is close to 5 dB. So you got to be careful with that radio when using the S-meter. Above S-9 it´s quite d
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
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
Just checked the WX0B website and his 4 SQ box. As far as I remembered it used to use the Lewallen current forcing method however now he is talking about "the new Lahlum" method. Anyone know what tha
