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

An excellent mount for my VW Bug hatch, fits perfect, good hardware and simple to install, love the adjustments to keep the antenna perfectly vertical. And the skinny lead in coax is perfect for the entry, no leaks and its been working great now for a month.

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.

So far it seems to be doing the job. I am not sure it has a good enough ground. Have not been able to check swrs yet either due to weather conditions. UPDATE: 4-4-17 This mount has caused my swrs to be the highest I have ever seen. I have raised and lowered the antenna and the swrs seem not to do anything...better or worse...it does nothing. The mounting screws are hitting bare metal so I guess it has a ground. Something isnt right, and it could be me, but I have had other mounts in the past, and this one does not seem to work with my dual band diamond antenna (2/440) As of now, I cant suggest this mount without knowing how to get a good ground to it. You will not get this problem with a mag-mount, which I guess I am going to have to get since this didnt work out. Total waste if money...it is missing a crucial ground and I dont know how to get it right.

Works great on the trunk for my 2/44 antenna

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.

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.

Excellent antenna mount, work perfect.

This little lip mount was easy to install on my Subaru Forester 2010. Be sure that you ground it properly if you decide to buy it. Ask your local hams for help if you need help installing it, that’s what they’re for. My only concern was what I’ve been seeing a lot with newer uhf style connectors, and that is that manufacturers are not filling the part that separates the inner conductor and outer with much. There is nothing but air and a small bit of plastic between the outer and center conductor. I’m concerned how well this mount will hold up in the weather over the long haul, but I haven’t heard any complaints from others. Also I checked just now my magnount has the same issue and it’s been holding up for about 4 years now.

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

Very well made and worth the money. After breaking two knock off mounts I ordered this mount and have had no problems since. Mount is sturdy and locks into place once tightened down. Perfect for my jeep. The knockoff mounts do not do this. I wish I had purchased this mount in the beginning.
