Comet CP-5M Universal RS-730 Lip Mount w/Coax Attached

I had high expectations for this coming from comet. Usually they have good products, but not this one. I mounted this on my Nissan Altima trunk for an MFJ 1538. Initially it seemed to be working well, but after an electrical storm, my tyt 9800 receive was fried. No chump change in this loss. I then hooked up a cheap leixan and then that got fried. (This was after i had to get a replacement coax assembly from comet because that came apart) in neither case did i get directly hit by lightning. Turns out that after grounding the mount directly, the antenna would not function. Remove the ground and it works again. This test is the basis for my assessment. The mount system can only ground through the radio. So if you get any emp or surge, the cars chassis does not absorb, it goes through your radio and burns out whatever is in its way. I should have went with my first inclination to drill a 5/8 hole and direct mount like i did with my ford explorer and another MFJ 1538 for my yeasu ft8900r and avoided the price of this plus $400 in radio equipment. Save your money. Get something that grounds properly or direct mount your so-239 and NMA antennas.

Worked perfectly for the mounting on the tailgate of my fzj80.

Overall this is an okay mount, I use it with a CSB-770A antenna. This mount says it will ground using the set screws, but because they powder coat/pain every surface after machining the mount, you need to take the mount completely apart, and scratch paint on each section, so the connector will be grounded to the screws, which in turn are grounded to the car. Then you need to scrape pain on the car where the set screws make contact. Overall this takes about an hour, with a knife and an ohm meter. Once thats done, everything works well.

Put this on my truck, on on the engine hood, a friend of mine recommended that I add a chassis ground wire to help make sure the antenna is grounded. I have had problems whatsoever with this.

This is the second one of these that Ive bought. I was impressed with the quality.

The core of the large friction washer broke out after less than a year installed on my 4Runner. Most of that time there was no antenna installed on the base (HF only occasionally) and it was even more rare for me to drive with it installed (ATAS-120A). I will be buying another one for parts to avoid having to completely tear apart my headliner to re-run cable, but I cannot recommend.

Awesome. Easy to install, no movement to rub paint. The functionality is wonderful due to the ability to move an antenna up or down as your circumstance requires, the top portion pivots. My Ham antenna shows perfect reception.

This a great setup for my 2013 Subaru Outback. It is fully angle adjustable and fits right into the upper left corner of the hatch back. The wire/cable portion that passes through from outside the vehicle to inside is small and therefore accommodates any closing “pinch.” The only “buyer beware” note I would make is in antenna attachment. In order to attach my Firestik II antenna, I need to buy an adaptor. Here’s the note from the US rep who was very helpful, “The adapter you need to turn the existing SO-239 connector on the mount into a 3/8-24 socket to accept the 3/8-24 stud on the antenna is model: AD-35M” Apparently there is a model of this lip mount that would have directly accommodated the Firestik, but Amazon failed to point that fact/choice out in their write-up. All of that aside, it’s a great piece and I would recommend it.

Great mount. Bought 2 of these to go on each side for a 2M/70cm antenna and a CB antenna. they work great and easy to install

Excellent antenna mount, work perfect.
