I have misplaced my instructions for my EF240X. I had to rebuild it after one element fell off and getting down and unbalanced antenna was a bit tough on the other element. I am looking for the start
Thanks Tom. I had forgotten about the opposite mounting. I thought there was something in the text about where the tuning jumper was supposed to go as a start and that is not on the drawing that I co
I got a note from Mark (the new owner of Force12) with the info I needed. The ref jumper is nominally 22 inches from the support. The DE is about 30 inches for 7.050. Thanks all. ____________________
Good advice. I left the original cable clamps on the first year but they were too much trouble and switched to stainless steel for my EF240X and 80m rotatable dipole.The stainless steel ones have bee
I found mine at Home Depot (about $5 a pair for the 1/8th inch ones now as I recall). Other places might be boating shops that sell sailing supplies. 73, Larry W6NWS -- Original Message -- From: "Dic
I believe it was the Polyphaser book that suggested that ground rods should be spaced no more than twice the length of the ground rod. So, for common 8 foot ground rods the spacing should be not more
As I recall having the rods too close was less effective in its ability to dissipate the strike charge. It wasn't a pure resistance idea although that is also a consideration. It has been awhile sinc
I found some at the local Home Depot as part of a package of 2 cable clamps and the thimble ($4.90 +/- for 1/8th inch package here). Someone last week also put up the URL of place selling clamps sing
I had an EZ-way tower at one time (72 footer). The WonderPost was about 10 (+/-) inches in diameter as I recall and about 10 feet tall. At the top of the post was a hinge where the tower was bolted -
I ran an HF6V (with 160 coil) on a 4 foot chain link fence for CQWW one year and it worked quite well despite the fact that the base of the antenna and top of the fence were about 5 feet below a road
The white conical insulators are usually called standoff insulators. They are usually used with balanced feed lines, _______________________________________________ __________________________________
I also use two thrust bearings above the rotator. I have a 20 foot mast with 3 antennas above the tower and it worried me that while working on it it might get away from me. The two bearings are a re
Wood towers were made back in the 1950's. The last one I recollect (at least think I recollect) was probably about 1958 or 1959 QST. I am not at a place where I can look up such articles. Some of the
A crane may be a good choice if you have the access. I had a 75 foot crankup tower at one point that needed to mount atop a big pipe-like structure. It took a crane operator all of 30 minutes to get
I have a KenPro KR2000. Yaesu bought out KenPro many years ago and the KR2000 was converted to the G-2800DXA. I had a problem where suddenly the rotator seemed to have limited rotation looking at the
I use two because I have a 20 foot mast over the tower with 3 antennas and it gives me a better feeling that the mast won't twist out of vertical when I pull the rotator to lower the mast to get to t
FWIW I have used NEMA4X fiberglass boxes for many years at the top of the tower. I use the gasketted, hinged cover with captive screws type box. They work very well and have survived several years of
I use a Kenpro KR2000 (built before Yaesu bought out Kenpro rotators) which is essentially the same as G2800DXA and I have always used a standard rotator plate with it on 25G, 45G, and other towers.
The spacer washers that come with the rotator are about 3/16" thick - thicker than a normal flat washer. I don't think it matters so much for the mast bracket. It does matter if you put the rotator o
I had a copy of the article and sent the dimensions direct to Joern. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@c
