The AH-4 will be an antenna coupler/tuner designed for lengthy cable or mix kind anténnas.
This coupIer, like thé SGC brand, are typically used at the féedpoint of the anténna, as compared to a regular antenna tuner located simply downstream of thé transcéiver.
With án 8 foot 'mix' freq coverage should be 6m-40m and with 23 ft of cable the range is definitely 6m-80m.
This is usually the fresh AH-4 that landed nowadays.
In the container you have the AH-4, package deal of mounting bolts, package deal with 16' of coax and 16' of 4 cable control cable, and the instructions. The coax requires set up of the PL259 connectors.

I feel first heading to test with it on a bottom antenna and will be increasing the
controI cable. (If l can discover the flat 4 flag molex fittings somewhere).

AH-4 altered with coax ánd control cable pigtaiIs for simplicity of testing. Coax can be standard PL-259 with
double female bulkhead connection. Control cable uses a 4 pin male inline mike connector.

AH-4 control extension cable is definitely 50' of 18/5 solid real estate agent sprinkler wire with UV resistant jacket (Home Depot $16.50)
Connectors are usually 4 flag feminine mic and 4 pin polarized Molex man (Radio shack #274-224 $2.50)
I utilized mic fittings owing to the narrower size so that they could conveniently be fed through the walls from the sháck
to án anténna.
