![]() "Bob" wrote in message ... Hi Steven Thank you for your response to my problem. Any suggestion? What you say is that I would be better off without that 1:1 balun? Yes, now I have it at 66feet each leg for a total of 132 feet but now it is not at the best height but kinda sagging and lopping where it is but off the ground and about 2 feet above the roof and other obstacles. I also have it presently close to steel guy wires and the tower itself. What would be my problem then here now? You believe it is my balun? The balun is basically what is limiting your multi-band operation. At crazy impedances the balun prevents the shield of the coax from assisting in absorbing some of the mismatch. Others have pointed out that the optimum situation is to feed your antenna with balanced line... if you must use coax, and you must have multi-band operation, then use an antenna tuner without a balun upstairs. RG58 doesn't work nearly as good as RG8... I couldn't make my inverted vee (resonant at 3750kHz) work 15m until I switched over to RG8. You should avoid legal-limit operation on the higher bands with this setup, unless you like burnt coax. I was hoping to get this up there and then leave it. All this climbing is difficult. Do you believe that once I get it up there, with the coax, with the dipole, no balun, do you think that would allow me better results with a good antenna tuner? Any advice is greatly appreciated. Yes, the good antenna tuner is the key. Get one with a built-in balun, so you can try balanced feedline when you get a chance. It really is hotter, both listening and transmitting. You should only climb once, put up a yardarm, rope, and pulley, and then you can play to your heart's content. Mounting a wire antenna permanently is pure hubris, beware! __ Steve KI5YG .. |
