What do you think about using a quarter wavelength shorted stub, made with coaxial cable, as trap for an 80m + 160m inverted L? 15.6m of RG213, shorted at one end, will block 8; /archives//html/Topband/2005-04/msg00094.html (7,615 bytes)

On 80 meters it looks like a 3000 ohm resistor. On 160 meters it looks like a 50 ohm inductance with a Q of only 25, which is 2 ohms loss resistance. will represent a; /archives//html/Topband/2005-04/msg00096.html (8,736 bytes)
