Jeff When you tilt the tower over, would you be near an overhead support like a tall structure or tree? If so, perhaps you could use a block & tackle attached to the tree (or structure) to take the w
For the base of my crankup I just used a 4-foot bubble level. I checked the level in both directions on each leg (ie. first measured with one end up, then with the opposite end up), and split the dif
For my 165' of 3" conduit, I used a shop vac and a spinning reel. Tied the handles of a plastic Safeway shopping bag to the 8# test fish line, released the reel, and using the blower direction on the
I used #2 stranded on my tower ground. As I recall, that's what US Tower recommended. 73, Steve N6SJ I personally think solid wire is better, but when you're talking about #2 solid, stuff that big ge
Dave I only have experience pulling multiple runs of small Heliax and control cables through a much larger 3" conduit. But based on what you're describing, I think you will need to pull out the coax
I use True Ladder Line at trueladderline.com, 16 ga. stranded insulated wire with about 4" long polyethylene spacers. I think he said it's 600 Ohms. I've used it on my 80M dipole for many years to op
Hans My 89' US Tower crankup has 2 anchor bolts at each leg, a total of 6 bolts. Each bolt is 1 -1/8" diameter and 27" long of ASTM grade 36 steel. I think I'd trust US Tower's licensed PE wet-stampe
Mark For many years I have used an 80M dipole strung between two fir trees and fed with open wire line (not ladder line). A tuner allows me to use it from 10M through 160M. Running 100W, I used a lit
Pete I've had good luck with the longer approach. I put a 30-150pF variable cap in series with the feed point and nulled the SWR at 1830 KHz. I have only two elevated radials (each 135') but it tunes
Bob I've used an M2 Orion to turn my SteppIR DB42 on my HDX589 with no problems the past 5 years. And we get pretty good winds here on the Skyline ridge facing the Pacific. 73, Steve N6SJ OK, we have
Brad I use a crossbow with two 16p nails taped to the tip of the arrow. The back end is tied to 8 lb fish line on a spinning reel mounted on a stake at my feet. I don't try this if there is any signi
Don I use your technique here on tall trees. Besides minimizing abrasion, the pulley allows the treetops to move in different directions in the wind without breaking wires! It's fun to watch the coun
Mac I have a UST HDX589 with a SteppIR DB42 (240 lbs., 20 sq. feet wind load) on top turned by an M2 Orion 2800 rotor. No problems in 5 years, with pretty good wind gusts here in the Santa Cruz Mount
Grant I think I learned about figure 8 flaking from your posts on Tower Talk! It sure does help avoid problems. 73, Steve N6SJ --Original Message-- From: TowerTalk <towertalk-bounces@contesting.com>
All, Regarding a tower resource, I learned at Visalia that Remigio Fernandez has returned from Venezuela, and back at work at US Tower at his old email. He is a CA-licensed PE and is extremely helpfu
Pete, My experience with that exact arrangement is that the wire through the pulley finally frays, and it breaks. Took about 2 years for my Inverted L to break. I had a pulley on a Douglas fir limb u
Matthew, Having managed the installation of numerous towers for cellular and public safety microwave links, I'm pretty sure you'll need to add torque arms (star mounts) to control the twist and sway
I agree, an exterminator is the best idea. We had a hornet's nest on the overhang of our house. I used about 3 cans of that 20'-distance spray to no avail. The local exterminator suited up and took c
Motorola's R56 is the gold standard for commercial communications sites. We had to comply with it for all our microwave radio installations for cellular, public safety, etc. I should apply it at my h
Keith, LDF5-50A is only .2 dB per 100' at 30MHz. LDF4-50A is about twice that. Which do you have? 73, Steve N6SJ About 20 years ago, after erecting a 150 foot tower (Rohn 45G equivalent), I was inspi
