ok, now i am getting somewhere! first this, i have several cheap
portable am/fm/sw radios. specifically i have sangean ats606, sangean
ats505 and sangean ats818. all have built in antennas and plugs for
external am/sw antennas. i am experimenting with a loop for a versatile
portable antenna. i know that it wont beat an outdoor antenna, but i
want something portable that beats the built in antennas. i am trying to
make a loop for am(mw) and a loop for sw on the same form with a common
output. i could switch the am winding or the sw winding in as needed.
the high or low impedance quality of the different styles of output
winding is interesting also. the high impedance would be useful on sw
when the whip is the only place to connect an antenna to. thanks to all
for their opinions!
