For square foundations it's probably best to rent a bender from a construction equipment rental company but for a cylindrical foundation, an EMT conduit bender works great. BTW, something I didn't re
Hi Nick, I have a 4' Andrew dish (aluminum) and I painted it with regular, gray, zinc-rich primer... same stuff I use on steel. It' Hi Geo, The older I get the more things that "was".;-) Thanks for t
Sorry about that... hit the wrong key and sent an incomplete message. Here we go again: Hi Nick, I have a 4' Andrew dish (aluminum) and I painted it with regular, gray, zinc-rich primer... same stuff
I did basically the same thing but used 4" ABS. The DWV sweep fittings are inexpensive and available at the local home center. I used a combination of a 90 and a 45 on each end, and as Gene says, don
When I first installed it I made some wire "plugs" out of that stiff metal screen like you find on soffit and crawlspace vents, but since the other end terminates outside the crawlspace I decided if
I originally used a fish tape to pull the first cables through. When I pulled them I included a nylon cord for future pulling. Every time you pull a new cable, just include another cord. 73 - JC, K0H
Greetings fellow TTs: As my new tower gets closer to going up (still have to clean out the bottom corners of the foundation hole, but it's been over 100 deg. F here lately) I am thinking of my old to
I'm using copper tubing, run inside garden hose while above ground, for my tower grounding "straps." I usually do the same thing (flatten the ends and make large terminal lugs out of them), but where
I don't know the diameter you are dealing with, John, but I have cleaned out 2 & 3-inch conduit by tying a big rag to nylon cord and pulling it back and forth through the conduit. You'd probably want
Greetings fellow TTers, Man, has it been hot out here! 139 deaths due to the heat in the past three weeks. We saw 112 deg. F on the shaded patio one day and three or four days in a row of 110+. The h
John says: "Turning the antenna (even with an azimuth rotator) won't change the angle of radiation." I think he means elevation rotator. --Original Message-- From: towertalk-bounces@contesting.com [m
Hi Robert, For what you want you could probably whip something up from a few Home Depot parts, but you might look at WWW.WB0W.COM and see what they have. DX Engineering also has some parts you could
Steve, John & all, Thanks for all the reminders and suggestions. In my case the forms are required because I'm doing a pad and pier (sort of a 3D inverted T) foundation. I tried digging it (so I woul
I don't want to rekindle the whole tower climbing safety issue, just buy a good belt and strap. I already have a number of safety harnesses and a new shock-absorbing Y lanyard with gorilla hooks. My
Hi John, Yes, my plans call for ~6" above the soil level. I'm on a slight slope (3" - 4" fall over the 9' the hole covers) and I've been pondering whether to just do the top of the pier parallel to t
Spoken like an insurance salesman;^) I'm sure glad no one required insurance for the towers I've taken down (no 1100 footers, however). Our club is frequently offered towers, no charge, if someone ju
Jim, Did you build or buy the transformers (ununs?)? Thanks & 73 - JC, K0HPS connectors for CATV line. I have made several 2 meter and 440 transformers for use with CATV line. Use copper tubing from
Hi Cameron, You already know of the Yaesu 5500 (they also made a 5400 & 5600 that you might find used... check the AMSAT BB reflector) and the AlfaSpid. Two more heavy duty systems are by M^2 (http:/
You could use Scotch 88 then Scotchcote then another layer of 88. I did that to "repair" (more like "replace"... they were really shot) the plastic trap caps on an old HyGain tribander and it's still
I think Steve, K7LXC, who sponsors this reflector sells it, or something very similar. Seems like I got a roll of Scotch 23 (rubber splicing tape) from him back in the day and I think it's basically
