Product Description

HD80 MATCHING COIL

As with all high “Q” mobile antennas (especially on 40, 75 & 160 meters) the feedpoint impedance is quite low. This necessitates some method of feedpoint impedance matching. This matching can be done several ways. An inductor, capacitor, toroidal transformer or other method can be used.Because of the ease of use we recommend the shunt inductor. The GLA Systems Heavy Duty Matching Coil is easy to tune and will match our antennas in all cases. It can also be used to match other types of HF antennas with great success. 

The HD-80 matching coil is 2 inches in diameter and 2.5 inches long. The base of the coil is a solid piece of copper that is the full diameter of the coil. This copper plate has a 3/8” hole in the center that allows the stud of the mast to secure the coil to the mount. 

The coil wire is wound on a solid CPVC form. The coil form has a 1 inch hole in the center to allow the mast to pass through and secure the coil to the mount. This greatly increases the strength of the coil and also reduces coil vibration. 

The coil is shorted to ground with a jumper and coil clips that are provided with the HD-80.
