Hello the list,

    I have in the past used my 160 meter dipole as a vertical "T" by tying the 
feeders together and using a tapped loading coil to resonate and match the 
antenna. I could get a perfect 50 ohm match in this manner and it radiated 
quite well - Hartmut copied my transmission running around 100 watts. I have 
also used the same setup on 500kHz with a different loading coil successfully.

   Now I find that I cannot resonate the antenna - I can't eliminate the 
reactance no matter what the setting of the tap or the coil. The best I can do 
is an swr of 1.7:1 and at least 40 ohms of reactance. I have tried changing 
coils and still the problem persists.  If I do transmit this way, my signal 
seems to be down at least 10dB below what it was when the antenna resonated 
properly. Any thoughts?
