For 3/4 inch CATV hardline, I strip back the black jacket about 2 inches, carve out the foam dialectric to depth of about 3/4 -inch (easiest with a $25 coring tool), cut four slits in the aluminum sh
Jim, I've had experience with two Tic Ring rotors. My own is a Model 1022 of 1993 vintage that was unused when I purchased it a year ago and installed on Rohn 45. It worked fine first time and ever s
Jim, On my 98-ft. of Rohn 45, I have a 3-stack of 204BA, with the lower two fixed (30 and 65 feet), and a 1022 Ring Rotor at 83 feet, about 6 inches above the top set of guys, holding a Hy Gain Explo

I have seen the swage tools for clamping down on Nicopress sleeves for around $150-180 at marine supply centers such as Boat US and West Marine; this for the large hand tool (looks like bolt cutter)
Hy-Gain has the newer Ham 4 manual available on its web site as a pdf file: http://www.hy-gain.com/hy-gain/man/pdf/HAM-IV.pdf Only difference is the new one has the 8-pin Jones plug instead of an 8-b
The Rohn TVRO specs allow for a 6 ft diameter satellite dish, 48.9 sq. ft projected area, in 70 mph wind load, on an 80-foot tower with 50% guying -- with 3 guys at just two places, 40 feet and 80 f
One of my top boom support cables on a Hy-Gain Explorer 7-3 snapped. These four cables are attached on the director and reflector elements, 10 inches out from the center of the boom. The manual speci
Hi John, Had thought about that, but the beam is already in place on the tower and I would have to dismantle it on the tower and lower to create a new boom splice (there are trees around which preven
Ted, I have three 100-ft towers amidst woods of mixed hardwoods and pines that are 70-80 feet tall. One of these is a series-fed tower for 160 meters in a grove of 20 or so loblolly pines that are 45
Buy a bunch of double-barrel female coax connectors. Buy a CATV coring tool for around $20-30. Buy a box of all-stainless hose clamps to fit the hardline. Use a knife to remove a couple of inches of
Steve, How long does the tree last after topping? Won't that kill it? Do you install steps for future access for maintenance? How about using a Ring Rotor -- anyone tried this? I have lots of 80 ft.
I have a 5-element 10-meter yagi hung from a tall pine tree. It's not very high, just about 20 feet. I used a piece of 1/4 inch wire rope as a support cable. It goes up and over a limb and back down
Hi Mike, I think Richard had a couple of extra cables to stabilize things, going off diagonally or perpendicular to the main cable to other trees. Maybe the rotor wasn't inverted -- it's been a few y
