Here is the situation: have an inverted V for 80m and noise level is S9.. Not good really.... Hi Andrus, Put 1:1 BalUn at end of Coax transmission line as choke. This will isolate local noise from line input. Also, does your transceiver share a circuit (identified at the breaker) with a noisy appliance? Change circuits (go to another outlet that is on a different breaker). Do you have a good RF ground? This goes against much of the common lore of dipoles being independent of ground. True, the antenna alone requires no ground, but somewhere your rig is connected to it, and it can be a very poor connection to a very poor RF ground. This is a very common path for noise to enter your receiver. 73's Richard Clark, KB7QHC |
