The Outbacker or the Hamstick are not usually fed with 300 ohm line. I have never used either, but it is my understanding they are both designed for mobile operation and a 50 ohm feed. If you are planning to transmit with the Outbacker fed with 300 ohm line you will need a Balanced Antenna Tuner at the shack. Even with this arrangement, I would not expect very good results because of ground losses and a low radiation resistance at the antenna input. You will be feeding a very unbalanced antenna with a balanced transmission line. My suggestion would be to feed the antenna with 50 ohm coax, and adjust the antenna for the best match at the transmitter. And yes, you will still need to connect the antenna ground jack to some sort of ground. 73 Gary N4AST ================================================= So the ground jack is needed for matching. I thought that might be the case. The 300 ohm feedline was connected to an antenna tuner. Well I completed installing the antenna and it didn't work for sh*t. So I tore it down. Chalk one up to experience. Thanks guys. |
