Thanks for the comments on PPM's. They pretty much fall in line with what I have observed over the past few decades of using them. Probably about 35 VDC with a 200 foot loop of # 12 should give 1/2 t
Another advantage of the TH-11 is no traps to burn up in the driven portion (an LP cell). That plus having 12 and 17. seems to me like a pretty good tradoff for less than 0.4 db. Gene / W2LU -- Origi
Depending on where you live, to be really safe, add another0.5 " or so to the mast diameter for ice, although you're probably not likely to get ice and high wind at the same time. I've had "good luck
If we're really looking for more things to worry about you could add vertical loading caused by that heavy steel tubing, and colum strength. You may eventually decide to stick with wires in trees. Is
Nice idea but need spec's on the coil. Gene / W2LU _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http
I built a carriage/track system for my 100 footer. For "track" I use two heavy 9 (about 5/8" galvanized) cables held about 3 feet apart at the top ans bottom of the tower by two pieces of 4" steel 'U
As sailors say "getting there is half the fun". Designing and building a track system is great for a real DIY'er. _______________________________________________ _____________________________________

Hi Doug - I built a carriage system for my 100 foot tower. The tower is quite substantial and guyed at 30/60/90. What I do is lower to 90. Disconnect the 90 guys at the anchor and lower to 60. Discon
Has anyone tried interlacing a 6 meter yagi on a TH-6DX and/or got a good model of a TH-6DX that I could run in or rewrite into AO ? Gene / W2LU _______________________________________________ ______
AC or DC is the question. I have heard from several sources that the PPM's should be run from DC or else the brushes would not last as long as they might. I had run one for 30-40 years on AC, with sm
Thanks Jim, it sounds like you have a really nice setup. I've gotten to the point where I should be looking at something more like that. I have moved the power supply to the base of the tower, but a
For a long run, if you wanted to save some money, and you could put up with the other inconviences, and if you could find good 9:1 baluns, you might consider 450 Ohm twin lead. Gene / W2LU -- Origina
Just remember that if you use 259's be sure to seal them up good against water intrusion. Gene / W2LU _______________________________________________ _______________________________________________ T

Why not just clearly on the mark the mid point of one of the cross braces on the inside of the flat side which is next to the house. Then tie a piece of rope to the leg that is out away from the hous
There are planetary gear systems and then there are planetary gear systems. Granted that probably there are present day boxes that you can turn by hand, but thern I believe that technically speaking
Hi Phil - Just a suggestion you might want to loolk into - Evergreen trees have had a reputation of having an adverse affect on the operation of verticals. You might want eo look into it before you b
What's been he experience with the Yaesu GS-065 bearing ? Gene / W2LU I have two of these and have had three TB-3's or which one is still good. The TB25 has a much better fit and finish and is much s
Hi John - My two cents worth, just to keep the thread alive. I go the wire/450 ohm feeder/tuner route since it all fits easily in a suitcase along with a little radio, switching PS and a TU. My rule
