41. Re: Topband: PolyPhaser Model IS-50UX-C0 (score: 1)
Author: "Harold Smith" <w0rihps@sbcglobal.net>

The voltage from a lightning strike is mostly DC not AC. If it would breakdown at 1225 watts, then why does PolyPhaser rate this model at 2000 watts from 1.5 to 50 mHz. Also what is a quarter-wave a

Most of the time the tower is hit and the voltage is induced in the coax. A tall approximately 1:1 transformer. I checked the output of the high-voltage supply with my Techtronics 422 scope and it i

Dave, I did some measurements on the I.C.E model 305, 15KW unit. With a 51 ohm resistor at the antenna connection, I measured with the MFJ 259B analyzer an Impedance of 52 ohms and the reactance was

Hi Bob, Nice to see your comments on the reflector. They will come again ! ! ! It was nice to operate at BY1QH in '98 with Merv K9FD. Most contacts were on 160. It was interesting to hear the signal

Dino: The "Glory Days" of 160 could have been many years ago when there were perhaps fewer than 100 countries on the band. If you look at the ARRL DXCC 160 listings, you will see that there are well

If the "every body else" stations run legal power the illegal power from the "big guns" in that case is 1,5MW? The big differences in signal strength are generally caused by location and antennas, no

Hello Ozer, Are you measuring the VSWR at the antenna or at your transceiver? If you are measuring it at the transceiver, your measurement can be all over the place. This is due to reactance, Xl or

Hi George, I have to agree with you. Feeding an unbalanced load with a unbalanced feedline, seems to me to be correct with no current balun. I shunt feed my tower with an Omega Match. Works out great

There are so many questions as to when 160 is going to be open. I think that the best indicator of band conditions is my receiver. I have seen rotten conditions with low A and K index. I have seen fa

Jim, I don't believe that the DX Sloper would be a good choice for working DX on 160 meters. Outside of a contest you may be able to work a bit but you also may struggle. Your 3 section crank-up sho
