I have 2 crankups and 1 guyed tower. For the crankups I use an extension ladder with one of those U shaped attachments at the top which are available at the stores that sell the ladders. They keep th
Great idea Rob. The 259 switch being on the front panel makes it very vulnerable to turn on when the unit is in a bag or pocket. I have a couple of the little power plugs, one is 0.20" OD and the oth
Many years ago, Electronics magazine had a picture of an experiment to use a tree as a vertical antenna. The RF was coupled to the tree with an air core toroid. It looked like a coiled spring, possib
John, if I was in your shoes I would drop the idea of a guyed tower installed with guying as you describe. It will be a real headache to get it approved. I would go the self supporting tower route. I
Dennis, you did not tell us what the diameter of the drum is and I think therin lies the problem. Typical tower winches use large diameter drums to avoid crushing the cable. They require a larger mot
Bill: There are several posts concerning this problem on TT May 23. You can read them on the TT archive. Your best bet is to jack the mast up and pull the rotator out. If you have a second bearing in
Jim, obviously you are quite knowledgeable about antennas and have mentioned most of the factors to be considered. You did not mention the importance of the available ground system. If you have a los

My experience was the same as Petes. I tuned for max f/b on a remote signal from a signal generator. Looking up at my antenna at 65 feet, the shorting bar for the reflector is about the length of the
Chris: My friend K5IU, Dick Weber, in Texas has an excellent presentation which has been given at HamCom as well as other places. I have the 27 slide PPT and I am sure he would not mind me sending it
Steve: I just gave a PPT presentation for our club called "Antenna Hints and Kinks" In that are pictures and discussion of an attachment I built for plowing in radials plus much more I originally mou
p.s. If anyone wants to use this PPT for a club program you are welcome to. I would strongly recommend that you use a laser pointer as I did to high lite the item in the picture being discussed. The
Rick: My first radial plow was attached to a lawn tractor. It had a manual lift lever which could be reached with your right hand to the rear of you while driving. It was just a formed bar which pivo
A friend has a US Tower which has 4 10 ft sections. Total extended height is about 36 feet or so. It has a hand winch for lifting the tower and another on the tilt over fixture. We have no informatio
Thanks all. I have the info on the tower. TT comes thru once again, Hi. 73, Dan, N5AR _______________________________________________ _______________________________________________ TowerTalk mailing
Dan: The HyTower top tubing stinger is insulated from the tower top and connected to a wire which runs down the center of the tower to the base where it is connected. The capacitance between the wire
I should have mentioned in my comments regarding extending the HyTower that I do not use the tilt base with the small insulators. I use pieces of fiberglass pipe for insulators and gave up the tilt o
My 2 Hamsticks have 6-32 screws The tapped hole seems to be slightly oversize but that is what is in them. 73, Dan, N5AR _______________________________________________ ______________________________
Jim, I have replaced all the cables on my TX472 as well as remove the pulleys and replace the bearings working from a ladder. My tower does not have a winch or power pull down. I raise and lower it u
Andre: I had the problem of repairing a 57 foot 3" boom which had buckled. I removed the damaged section. I measured the ID of the undamaged tube and went to our local aluminum supplier. They had an
