Comet CP-5NMO CP5NMO Original RS-730 w/CK-3M5 166 NMO

I recently purchased this Comet CP-5NMO trunk mount, for my Mustang. The Browning BR-140 NMO antenna is fastened to it and into my Cobra 25 LTD. Because this is a trunk mount, the lid itself might NOT have a COMPLETE ground to the body when closed. I installed 3/8 wide copper braided wire on both sides of the lid, directly to the body. There were trunk and body bolts to attach the braided copper wire for solid uninterrupted possible ground problems. With this Comet trunk mount and the Browning BR-104 Antenna being perfectly vertical, plus the exceptional SWR, what more can you ask for.

I will admit putting it on and getting the antenna to stand up correctly took some time but it was well worth it. This mount stayed on and never needed adjustment. I used it 3 years until I sold the car. When I took it off there were no tell tale marks where it had been. I reinstalled it on my new truck with out any trouble. I have a 2m/70 cm antenna on it.

Bought a glass car and need to have a hatch mount for my cx-224 antenna. 1st time using it seems pretty sturdy even with my tri band antenna on it.

We certainly like the mount. However they barely fit the lip of the rear hatch on a Dodge Journey. They fit, however just barely. Grounding is an issue and loss of paint from opening and closing the hatch. The second mount we received had a loose NMO mount insert that we had to secure. The insert became lodged in the antenna and we had a heck of a time removing the insert to reinstall on the NMO mount, with thread lock. All in all, it beats drilling holes, dropping headliners, etc. You have to keep a constant eye on these mounts, but they work.

Perfect use for my low band and VHF antennas to still be able to fit into my garage. Works awesome that they mounted right to the side mounts of a BackRack

Much better than the last one I purchased [10 years till no longer functional] hold downs, positioning .. this time bolts.. far improved over hex key screws! Nice unit!

The hole in the lip mount was too small for the included NMO antenna base to fit into. It required drilling the hole out larger, which was quite difficult.

I remove the antenna and cover the mount with an NMO rain cap when I go through the car wash. I also switch between a 1/4 wavelength and 1/2 wavelength antenna, depending on terrain. About 40 antenna length for the 1/2 wave. I grounded the mount to the hood, and I achieve about 1.2 SWR at 145.460 MHz with the 1/4 wave antenna. I am very pleased with the mounts performance.
