Grounding hf antenna
WebNov 29, 2016 · Since the end fed wire is in the air it still can benefit from an RF ground "plane" underneath the antenna. This RF ground "plane" should be connected to your station "single point ground" and also be connected to your "Electrical" safety ground. This RF ground could be a single wire strung out parallel and underneath your antenna wire. Web4. Eliminate ground loops and multi-point ground connections when possible. A HAM shack ground loop gives lightening another path to your equipment. Always use a single …

WebExcept this one in no way acts like one at vhf/uhf frequencies. 2-3 turns in a 3” circle for this antenna to be effective. 8-9 turns (or more) at a 6” diameter for HF, this is only 2 turns at around 18”. Must be a service loop or maybe he plans to raise it higher. WebThe key to end fed antenna success is the matching network interface between the long wire antenna and the coax feed line and feed line choke at the transceiver. Palomar Engineers employs a dual core matching system that offers wide bandwidth (1-61 MHz), 500 watt PEP rating, and a connection for a counterpoise or ground if desired.
