Why copper pipe for antenna?
I’m seeing plans to make 3 meter outdoor antennas and copper pipe is used. I think I read that the bigger the diameter the better. Is there a limit to diameter? Why not a 3 inch diameter vent pipe like leaves my gas water heater? Would a solid grounding rod work as well as a pipe? …Yes, I know nothing 🙂
Will 2 transmitters interfere with each other?
Hey,
Hey,
I’ve not bought any transmitter yet and the long goal is an AMT3000 (or AM88) but for starters I’m thinking of building a VEC-1290K. If after building it and monkeying around I really want to invest myself into LPAM, can I broadcast on two transmitters (different freq’s) from the same location or will they interfere with each other? How far apart would the antennas need to be? I believe I read that some particular transmitter chews up the surrounding frequencies with its square wave noise. Which transmitters would that apply to?
