Problems with your vehicle's ground plane / SWR? Add this RF choke where your coax cable. Attaches to the stud/antenna mount to cut down on RF on the outside of the coax shield (common mode currents) and improve your antenna system
This RFI choke from ABR is an effective tool for mitigating radio frequency interference that may be picked up by the coaxial cable. They help to suppress common-mode currents that can be induced by nearby power lines or other sources of electromagnetic interference. By reducing common-mode currents and unwanted RF signals picked up by the feedline, an RFI choke can improve the signal-to-noise ratio of the received signal. The result is clearer reception and a more efficient antenna.A lot of newer semi trucks are lacking a sufficient ground plane because of modern build designs. This causes plenty of headaches trying to get an antenna's SWR tuned in and creates a lot of unwanted noise. When an antenna lacks a ground plane, it may suffer from impedance mismatches and can radiate energy in unwanted directions, leading to poor efficiency and performance. An inline RF choke can help improve the performance of an antenna system lacking a ground plane by reducing common-mode currents and improving the impedance matching between the antenna and the transmission line, leading to better efficiency and performance of the overall antenna system.
