Does any tower mfr make a 100' crank up monopole? I like the US Tower MA850, but want a full 100 feet of height. 73, Steve N6SJ _______________________________________________ _______________________
I am looking for a contractor to furnish & install a concrete foundation for a crank-up tower in the Redwood City, CA area. I want someone who has experience with towers, not just pouring slabs for d

Jerry I just received my building permit from San Mateo County for a US Tower HDX-589. The County Building Dept. accepted the CA PE stamp and signature on the front of the .pdf copy of the structural
I called our local ARRL volunteer counsel and he told me the high fees at San Mateo County had been mandated by the Board of Supervisors to recoup some of their lost tax revenues caused by the recess
Grant I agree. The key is to obtain the original code/ordinance language and understand it. I found most of the counter staff at the County were not at all familiar with the parts of their own code t
Eric I used "flooded" RG6, like the cable TV companies use for direct burial. I understand they are going away from direct burial and toward conduits for the purpose of easier maintenance, but in you
Mike I'm not a naysayer, but I'd have one simple question: What would be inside the fall radius of your newly designed tower? If nothing you're worried about, go for it, sounds cool! One thing you mi
Damon I just obtained a building permit for my tower in San Mateo County, so you probably want LA County hams to answer your question. But it appears from the ordinance that if you meet all the requi
I have a 80M dipole up around 70 feet fed with open wire line just like yours. I have worked a few countries with 100W feeding the shorted feedline through a tuner. I have no counterpoise or radial s
That's the one I built for 20M in the early 60's and worked around 200 countries on it pointed at 20 degrees azimuth from Sacramento. It was strung between my house and a tree in the backyard, up onl
I need to install underground conduits to my new HDX-589 crank-up tower. The distence between my garage wall and the tower foundation is about 125'. I plan to put in straight conduits with a 90 degre
Thanks to all for your comments on my new conduits. I'm now thinking the LDF5-50 sounds like it's hardly worth the hassle for a few tenths of a dB at 30 MHz. Do many of you have experience with LMR 6
I'm about to place a number of 150' Sched 40 PVC conduits between my shack and new tower. I want to end up with small 200 lb. stength nylon twine in each conduit, then use that small twine to pull th

Can anyone suggest a good source for 250' rolls of Cu wire? I need to pull four conductors of stranded #10 Cu wire through my new 220 feet of conduit. I need four colors, black/red/white and green, s
Jim Here are a couple of pictures of how I installed my mast through a Rohn 25 pointy top sleeve. The rubber pipe adapters for cast iron/plastic pipe are available at any Home Depot. I had to use a r
Ed Do you know the voltage actually reaching the rotor? When I had this problem with a Yaesu rotor on a long run of cable, I added a "boost" AC transformer in series with the rotor line at the contro
I'm getting ready to pull wires and cables through the conduits to my new tower, and I want to include an additional pull rope for future cables. My 3" ID conduits will be initially very lightly load
I used a 5V filament transformer to boost the AC voltage on my old rotor years ago. I put the transformer in a small box next to the control, and wired it into the rotor control housing, wiring the t
