[ARC5] Antenna for small yard

[K5MYJ]

The ARC-5 transmitters have a built in antenna tuner. It is the rotary 
inductor in the front of the transmitter.

These transmitters were designed to operate with an untuned, non-resonate 
antenna. The antenna starts directly at the antenna post on the transmitter. 
There is no feedline.

If you connect the antenna wire directly to the transmitter (like it was in 
the aircraft) you still need a good ground.

Run a wire from the transmitter chassis to a ground rod below the window you 
run the antenna out of.

The ARC-5 system used a RF Ammeter to adjust the loading coil.

Don't expect much in the way of DX. This kind of system is meant for short 
range (local) operation.

The bombers used the liaison set (ART-13, BC-375, etc) for long distance 
communication. The Command Set was intended for short range plane to plane 
to plane to tower.
