close to the telescopic aerial would work - probably better without the earth connection as for MW use. A shortwave tuner would be better, and could be earthed. As always, to minimise the risk of static damage, you need to be sure there is no direct connection from the longwire through the tuner to the telescopic aerial. You can check this with a meter. If in doubt, always use a loose insulated-wire wrap around the telescopic aerial instead of a direct connection. This may in any case be preferable to avoid overloading the receiver, which is designed to work with a short telescopic aerial. Michael UK ----- Original Message -----

Thanks Michael, that's a bit dissappointing to hear that Shortwave Listening may NOT work with the 2 Loopstick / 2 Capacitor Inductive Trap you designed to work off my Longwire Antenna to prevent Receiver Overload. Along with the MFJ 16010 Antenna Tuner that I have, a friend of mine recently loaned me a Shortwave only Joymatch III Partridge Electronics - (Broadstairs Kent England), its frequency range is from 1.6 to 32 MHZ. So would I have to switch back from one to the other for MW and Shortwave listening? Thanks. |
