"Vito" wrote "Ken" wrote Do I need a dogbone or egg insulator at each end of my dipole, or can I just splice the antenna wire to the nylon braid that runs to my trees? Answer: maybe. The nylon braid is OK so long as it never gets wet and absorbs water or if you let it thoroughly dry before transmitting. I bought my XYL a high-$$$ all-band vertical and a tuner. It rained hard one night. The next AM she noted that she had to retune to get the SWR normal but she fired up her 100 watts and made several QSO's. Then she barely heard an old friend signing off with another station so she turned on her 'killer-watt' and called him. They'd barely got thru exchanging calls and into the pleasantries when she noticed a smell ..... luckily only the tubes were fried. She turned off the amp and saw that the SWR was out of sight - until she returned the tuner to it's usual settings for that freq. I was soon swinging from the trees installing dipoles for each band -- with insulators! Hi Vito, I don't see any connection between frying tubes on an amp from an "all band vertical" with tuner settings that were not "it's usual settings for that freq", and having no egg-type insulators on the ends of a dipole - did I miss something here? I never installed the eggs on the lower antennas (fan type) of my dipole (ran out of them at the time), and when it offered SWR of 1:1 performance dry or in pouring rain, I just left the original copper wire to nylon line tie-off alone. Been up for a year with no problems ever. Jack Uh, OK if you get away with it. But you do know that the highest currents are at the ends of a dipole, right? Hence, you *could* set something afire! No joy. 73 |
