VHF Permanent Installation


The JT1B antenna found its permanent home.  A 4x4 3 feet in the ground with 100lbs of concrete around the base.  Rises 7 feet in the air.  Attached to this base is 2 - 10 foot top rail fence segments getting the bottom of the antenna up to 20 feet.  So the bottom is at 20' and the top is at 36'.  Hopefully this will get it high enough for good simplex communications and out of the RF shadow being caused by the house.

It connects back to the house with 100' of LMR-400 cable.  Tests indicate the SWR at < 1.1:1  .
