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

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.

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.

This is my third unit. I have used them since my 2006 Prius and the latest is going on my 2020 Tesla. Makes mounting and running the cable as easy as possible.

The best product I’ve ever bought. The smaller feed line section closest the antenna was a brilliant idea. The mount itself is well made and heavy duty. I put my SSB2 NMO antenna from Comet and I was full quieting into our Club repeater. I got tired of my roof mounted with drilled hole getting knocked of and finally making me have a body shop fill in the hole and repaint roof. The only challenge is getting an Allen wrench to tighten the small set screws. Highly recommended product. N9NY Fast forward three weeks. I broke the tightening wing nut that locks the antenna angle into place. Ugh! E-mailed HamCity who sold the antenna mount asking what can be done. HamCity contacted Comet on my behalf and four days later I had the replacement part at no charge. That’s great customer service! Thank you!

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.

I tried to use this as a rear door mount on a 2019 Toyota Tacoma. It is heavy, but the device seems to secure to the top of the door very well. BUT the problem is that it sticks out and catches all kinds of wind noise going at highway speeds. I tried turning the top of the unit around, but the knob to tighten the antenna is so big it pushes against the roof. Im hanging on to it in hopes of convincing my wife to let me attach it to the trunk of her car, but as a door mount, I just cant recommend it.

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

When it comes to similar trunk lid melts, this one has a larger, more bulky appearance in the more slim line version from Diamond. I do like the fact that has the larger more insulated coax cable for a majority of the installation, but I had a hard time getting the PL-259 adapter off the coax cable in order to run it through the vehicle. Also had a hard time with the junction of the two coax cables wanting to curl and kink constantly. Have concerns for longevity. Returned it and went with a diamond trunk lid mount instead.

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.
