Re: Same feedline


 

What impedance does a SHORTED folded dipole @2m present to 6m (or 6 to 2 for that matter)
Interesting....

John,

I'd suggest using a Diplexer, instead of a coax T connector.? That way, you don't have to worry about the problem of what kind of impedance the un-used antenna will have on the in-use antenna.? There are duplexers that will separate HF thru 6 meters, from 2 meters.

Is it possible to feed two folded dipoles, 1 on 2m and the other on 6m, with the same coax and t connector at the top? I see some commercial dual band 2m/70cm ones that do this and it's a similar principal to a fan dipole where only the resonant antenna would let the RF pass. This is for repeaters on the tower so I wanted to tap this groups thoughts.
