Locked Re: Tuning a loop.
Does this mean there is no capacitor attached to the loop and all tuning is done by the ATU? So the resistance of the feeder is included in the loop resonance? If so, you could get higher Q and hence

Locked More on the "crude loop".
Jim, I don't even have to go out to the patio to make adjustments as my loop is mounted indoors where it picks up just as much noise as my whip antenna (36") and actually is capable of discriminating

Locked Re: Loop matching
Automatic tuning could be made to work, but you will have to furnish a pilot carrier for the coupler to know how to tune the loop. The SGC "stealth kit" is basicly a green camouflaged loop and support

Locked Re: Loop matching
Yes, it is certainly possible. ATU's are primarily designed to tune 2-30 mhz and go into the auto tune mode when they receive an injection of several watts of power from your xmitter. The larger the

Locked Re: Loop matching
Hi, An automatic antenna tuner works matching the transmitted signal of the transmitter to the antenna. If you are using it for this purpose it will work well. I am using an LDG AT-200Pro autotuner

Locked Loop matching
Hi, loop fans! I'm thinking of using an auto antenna tuner to match a HF square loop's internal impetance with RG58. Is that possible? Thanks in advance...
