I have a piece of Andrew 7/8" hardline with an Andrew 45J connector on the end of it. I am not familiar with this connector. What type of connector is it? And what type of connector would I need to c
Try CATS / Rotor Doctor - http://rotor-doc.com/ . He has gold plated connectors. Will never corrode. Ray, N6VR _______________________________________________ ________________________________________
The Tyco connectors in the Mouser catalog are the same ones that Rotor-Doc uses/sells. N6VR _______________________________________________ _______________________________________________ TowerTalk m
I used the C-J connectors for awhile, however, after time and rain, minerals built up on the contacts making them intermittent (I did try to water seal the CJ connectors). You'll never have that prob
Jorge, I became owner of a MA770 that had not been raise or lowered in perhaps 10 years. I found most of the cable pulley roller bearings frozen. I removed all the bearings and soaked them an ultra-s
Jorge, The tower looks to be in good condx. The only thing that looks questionable is the rust on one of the lifting cables. If it is only surface rust, I'd clean it with a wire brush thoroughly then
This may be better suited for towertalk. There are many good antennas and rotators to choose from. Regarding the controller, I have six Green Heron control boxes currently in use and I could not be h
Fred, Very interesting! My questions: is there a way to relate this information to separating corroded Aluminum? Guess I'll be trying the homebrew ATF-Acetone mix next time to separate Al tubing. Ray
Steve, I have a TWS-771 in the air at my new QTH in AZ. Prior, it was in the air for 25 years in CA. The info I have on the tower is rather skimpy, but it does show the cabling scheme. Do you have th
Rich, I recently bought a Gorilla hook assembly from GME Supply Co. They are a commercial business that supplies climbing equipment & gear to the climbing professionals. Their Web site: WWW.gmesupply
Mike, I am not sure if you are intending to operate horizontal with an antenna on it, or just testing the rotator on its side? Like it was said, it will operate on its side, at least for testing purp
Clay, I remember in the old days that 10 % of the pole needed to be in the ground. At the old N6DX contest station, there were two 80 - 90 ft poles, but because of the large antennas on the poles, th
I agree, Al is not good direct buried. Al underground will deteriorate/disappear quickly, perhaps less than a year depending on the soil PH and moisture content. Ray, N6VR ___________________________
Rick, The pulley bearings do seize up at over time depending on WX and your environment, especially if the tower is left in one position for a long time. Tashjian Towers did sell replacement pulleys
I had to cut off a welded on gear from a 2" X .375" Cr mast - not easy. It was laying on saw horses on the ground and took me a day or two of on and off cutting/grinding with a 3 1/2" steel cutting s
The M Squared antennas do very well. They are not cheap but will hold up to almost anything. Their link: http://www.m2inc.com/index.php?ax=amateur&pg=45 They also have 3 and 4 el versions. I have a C
Jim, One question, why not crimp the center conductor, then solder? That's my procedure. Ray, N6VR _______________________________________________ _______________________________________________ Towe
Do a search for the ZL6QH Club site location. It was written up somewhere not to long ago. They had 4 - 5, windmill windmill monsters installed on hill tops hear them. The site is almost useless now
I have a MA770, 70 ft telescoping mast with a Ham 4 rotator mounted at the base. My problem, if I have any winds over, say 10 mph, the Ham 4 stalls and will not rotate my Force 12 10m-17m multi eleme
Arne and all, Tnx for the replies. Will have to go out and do more checking of my rotator connection and voltage across pins 4 & 8. I use the CATS, gold plated quick connectors so the connection shou
