Off Center Fed (OCF) Antenna Feed Line Choke for 1/4" coax (1.8-61 MHz)
Got an off center fed antenna fed with RG-8X size coax and having feed line radiation (RFI) problems?
This feed line choke will help solve the problem of feed line radiation (which causes RFI to nearby object close to you coax) as well as Improving antenna pattern by preventing your dipole from becoming a tripole
Simple to install as an extension to your existing coax feed line using a female to female barrel connector (available separately).
Install quickly, reduce your coax radiation issues and start working more DX with a better transmission (and reception) antenna pattern.
Also works with single or multi-band loop antennas using a 2:1, 4:1 or 6:1 transformer without a choke.
