CMNF-5000HF for transmitter/receiver coax lines up to 5000 watts PEP - 1.8-60 MHz!
For coax feed lines with receive and transmit signals, you will love the small size, wide frequency range and excellent attenuation of common mode noise interference
- Reduces broadband common mode receiver noise* picked up on the outside of the antenna coax feed line.
- Wide frequency range works on all brands of radios and coax fed antennas from 1.8-60 MHz
- Common mode noise rejection up to 15-38 DB (2-5 "S" units) depending on frequency
- Simple plug & play installation: plug a short jumper from the CMNF-5000HF to your amplifier output and plug the feed line (or a jumper to your antenna tuner) into the other SO-239 CMNF-5000HF input. Either connector can be input or output. Rated at 5000 watts PEP.
- will work with Bias-T antenna switches and will pass DC voltage from input to output with no attenuation
* not effective for noise from AC power lines or noise received directly by antenna
Installation Note: For best results, and to reduce co-interference between choked and unchoked coax feed lines with multiple antennas, ALL antenna feed lines entering the radio room need to have a separate feed line choke particularly if they are at a different frequency then HF, like VHF or UHF.
if you use a antenna switch for multiple antennas in the 1.8-61 MHz range, place the CMNF-5000HF in the "common" line of the antenna coax switch and the antenna tuner/amplifier.
For additional common mode noise reduction, consider the CMNF-500HF (500 watts PEP) placed between the receiver and the amplifier.

Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications. Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc. You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.
A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common. The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.
THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
