Rick said it better. Thanks Rick. The T has been a great performer for me in 4 different locations over the years. I swear by it for 55 - 70 ft vertical sections. Ed N1UR When you model an inverted L

AA0RS was a real alligator out this way. Myself and others calling and not able to hear. He eventually called me after I kicked on the amp for the last 90 mins of my participation. Ed N1UR __________

Frank had brought up the interaction of certain T top loading wires and the possible interaction with yagis. I played around with modelling on this and found that just as Frank said, there is interac

Mike, I am not sure where you find your information, but ALL of the radiation of a T top vertical is vertically polarized assuming the T section is balanced. The whole point of the T is that the hori

Guy. Its interesting reading. But it makes A LOT of assumptions tied to your promotion of the folded counter poise. If, in fact, you have invested in a significant ground screen under the vertical fe

No attack intended. But his website is titled Folded Counter Poise. And that compromise ground system has a lot to do with his data. I dont have a folded counterpoise under my 160M Ts. ON4UNs book is

Mike and others. All you have to do is model it to see the result. The more horizontal component of an L, the lower the max gain of the low angle vertical portion. If you counter that with worse and

There is no question about vertical vs horizontal and also time of NVIS vs low angle prop. The question started about whether the L was the same as a T. Its not. However, ad Mark states, having 2 ant

I remember having some experience with that MFJ-1026 a number of years ago and found the trade off of increased noise floor vs cancelling not worth the effort. Trading one evil for another evil. Obvi

Hello all. If you are participating in the IARU contest this weekend, in addition to the 160M CW band, please also venture up to the SSB portion as well. It is often very difficult to get SSB Qs on 1

I believe the top output power in C6 is 250W. As someone who first did in band receiving on many bands up to 200W and then "graduated it" to 1.5kW, it a horse of a different color. I don't disagree w
