That is a great movie and I would love to see it again. Hopefully more copies can be made on DVD for a reasonable cost. John KK9A I have also received some inquires about the "To Win the World" movie
Since the balun is used on 20m and 10m, I think you can rule that out. I think this is the first time I heard someone complain about an antenna with a perfect match. John KK9A I new there was somethi
Rohn recommended a pier pin for my installation and it works great, however the tower obviously will not free stand. Why are you against putting part of a section in concrete? It's a lot simpler and
Yes you can use add a parasitic element (reflector or director) and create a vertical array. John KK9A I asked this same question here a couple of months ago, and from what I received in answer, I as
I seem to recall at one time Phillystran recommended using cable clamps. I'm not sure if this was done with the older style product. John KK9A Hi Guys, We are looking for some of these old style Phil
K4JA who is now QRT built a number of rotating bases and rings. You can see them at http://www.k4ja.com/ John KK9A [TowerTalk] Has anyone ever homebrewed a Rotating tower Base beforeand a from [ KZ4U

What optimum performance are you looking for? If you are looking for a specific radiation angle , I guess the software would put both antennas close to each other. The real advantage to stacking is t
110' is probably a good height for 20m. When sunspot activity increases, stations with a 30' high tribander will be much stronger than you on 10m. John KK9A OK, you guys are starting to worry me. I j
I have used a rotatable dipole and a beam on 40m and the beam is much better, in my opinion. I would expect the same results on 80m. You can read NQ4I's 80m four square vs. beam comparison in the arc
This is a tough comparison since you were much closer to the ocean than W4AN. Same thing applies to a well built 4 sq vs. a 2 el beam. I can't tell you much about one el vs two el, but I can tell you
I think the biggest problem is the antenna was much too low and it was picking up the local noise more than the DX signal. Mike: Tnx. kept missing some stations on 40/80 that were in the nulls of the
There are a lot of variables when using multiple antennas. A loaded 40m element may not have a 15m resonance the way a full sized element does and if you turn one antenna 90 degrees, the boom of the
Some coax cables, such as 9913, are more susceptible to water problems than other cables such as 8267 RG-213, so there is no way to answer your question without knowing what cable you have and how ex
That is quite a claim. Either the potentiometer or the drive gear is slipping, If it is the drive gear you may not have a tight enough fit with the motor. The main gear is not round and setting it ca
I have not seen any crank up towers that lasts in a corrosive environment. Steel guyed towers require regular painting and replacement of guy wires. Aluminum antennas also corrode, especially parts i
I have used a bungee cord connecting the bottom loop of the coax to the boom, holding the coax away from the tower. As the antenna turns it stretches out and the coax never rubs the tower, guys or an
I think mounting the coils out on the elements is better, however I would still keep them near the center where the element is stronger. Relays on antennas often fail, especially after being hit by l
Green Heron Engineering makes a nice prop pitch controller that provides 25 to 28 volts for the motor and it uses a pulse feedback for direction control. John KK9A I am in need of a schematic for pro
What is the purpose of end caps? I never use them and I have never had a problem as a result of not having end caps. John KK9A I am in need of some 3" plastic boom caps and some 1/2" element end caps
