This is Correct except you have left out the fact that you have an impedance other than 50 ohms driving it at the feed point. Your short antenna has an impedance of R-jX and the antenna tuner combine
I just looked at the RatPak users guide, no schematic but looking at the PCB there are protective diodes across the relay coils. Also it uses a multi-conductor cable. It is possible the multi-conduct
I have not been keeping track of this thread but do offer the following solution to the problem. Most antennas, even VHF and UHF beams have much more than 15 or 20 degree beam widths. One degree reso
If you have not had a problem in 4 years and now you do you may look into other electrical hardware on the tower. It may me lighting systems that have started to arc when there is heavy rain or some
Depends on how strong the bracket and anchoring is. We had a 25G for 30 years in Nashville with some very small guys and a house bracket at about 12 feet above the ground and over 40 feet above the b
I got some titanium coated drill bits once and was drilling a small hole in aluminum. It suddenly stopped drilling and I stopped the drill. It did not break but instead it bent at a right angle. Gee,
The problems still exist. How many parts in American Made items are made in China. Even the Department of Defense is having problems with poor quality or counterfeit parts in many complex defense sys
I have found that hardware stores and even walmart sometimes has these polyfoam brightly colored tubes that are soft and very thick for only a few dollars each. Kids like to use them as swords and th
Yes there is no free lunch. In fact the limits for radio waves and photons are the same as described by Heisenberg's Uncertainty Principle. The limit has to do with the range of momentum in the x dir
Not everyone knows that a tuner only protects the rig. That is the job of a dummy load. In fact the tuner matches the impedance of the antenna system to the rig and not only that, by doing so providi
I want to make something clear. I never said that is practical to match any load with an antenna tuner. In fact if you have an "anti-resonant" antenna it is a lost cause. I was simply debunking the n
After hurricane Andrew the standards for towers were rewritten to allow for higher winds. It had nothing to do with concrete or computers. I also have a Heights Tower, that I installed pre-Andrew, bu
