Simple Ham Radio Antennas--Winding a RF Choke. Post #978

If you're having trouble viewing this video, please insert this title URL into your browser search box:  RF chokes are used to prevent unwanted RF from entering your ham shack via the feedline.  In this video, N7JFP does an excellent job of explaining how to design and build a RF choke for VHF and UHF applications.  If you want a RF choke for HF purposes, just take some of the coax feed line near the antenna elements and wind about 5-8 turns into a 4 to 5 inch/10.16 cm to 12.70 cm diameter coil. Secure the coil with 3 to 4 plastic ties and attach it to the mast or supporting structure.
