Sloppy Standards

I bought this mount for a Recent road trip. The price was right and it was a mechanical piece of equipment. No electronics involved. What could go wrong? Other than tightening the magnets so they wouldn't fall off, all appeared OK. I set it up, attached a twenty meter hamstick and off we go. Initially all went well. On the second day of the trip, I find myself transmitting into a dead short. Nothing on the exterior of the mount presents a problem. Disassembly reveals center conductor wedged under a washer that is compressed by tightening center shaft. It had worked it's way free. The braid was fanned out and jammed into a small center ring for grounding. Properly terminated coax would include solder lugs to assure continuity. Some modicum of weatherproofing would be expected also. I fixed it and was on my way Unacceptable, shoddy workmanship. MFJ ought to be ashamed of themselves for putting crap like this on the market.

Got this for Christmas 2010. Came with 1 magnet not mounted to housing. The other 2 were mounted. Nut and bolt, and lockwasher all sealed beneath the mylar. Had to cut mylar and retreive these. Mounted, and put aluminum tape over hole. Workes fine. I should bill MFJ for labor.:(

It works fine, but it rusts in two years time, and needed repair.

It Sticks!
|
Time owned: 0 to 3 months

I've only owned this for a few days, but so far so good. No problems holding the Ham Stick 20 meter antenna at highway speeds. The only negative thing I've experienced so far is noise created by wind blowing over the car above 45mph. The combination of the Ham Stick and mount creates a dull whistling sound and I suppose the roof itself is acting like a resonator making it louder inside. It's not so bad that it's annoying, simply noticeable. In my opinion a good alternative to drilling a hole. My SWR of 1.4:1 is acceptable for this type of setup.

Strong mag mount
|
Time owned: 0 to 3 months

Recently purchased this mag mount from AES, works
great, no worries about the antenna coming off.
Once you put it on the trunk, or roof of your
vehicle, it is going to stay. 73's KM5TC

One of the better ones!

I have had several of the MFJ mag mounts, including the 336T. I have been using their mounts for about 4 yrs. now, and have not had one little problem in all that time. I have used a varity of antennas on them. I've had the Diamond HV-7A, the Tarheel II, hamsticks,etc. My current antenna i s an OPEK H300,(not sure bout the mod#), this antenna covers 40,15,6,2,70cm. and have had NO problems with it. I can attest to the fact that these mounts WILL hold up at highway speeds,70-80 mph. with no problem. It will even stay on during a HURRICANE! We had 4 of em here in Fl. a couple of yrs ago and they went thru the storms just fine.
Get one you wont be sorry, as a matter of fact when I get to Dayton you can bet my first purchase will be one of these babys. I need a new one for my hamsticks, gave the last one I had to a fellow ham who is moving to Va.

I just picked this up from commercial dealer at local swap meet. Got it home and the first thing I had to do was peel back one of the protective covers so that I could get wrenches on to tighten up the magnet to the frame. The other two required tightening, but was able to tighten from the top using only one wrench. Mounted up my Hustler 75M Super resonator on the Hustler mast and noticed that when I closed the trunk the magnets lifted slightly. I have another tri mag mount that has the same size magnets mounted on a T bar set up. I had my Hustler CGT-144 2 mtr collinear mounted on it. I ended up having to switch the antennas. The MFJ holds the 2mtr ok, but not the Hustler 75M setup. The HF on the other mount is very very stable no sign of magnets lifting. Maybe I just got a "Monday morning / Friday afternoon" mount. I was execting better. Maybe ok if using ham stick style antenna, but mine doesn't work well with my HF set up. Looking to get Tarheel soon so I guess it will be mounted on my old T-Bar mag mount.

Appears similar to other 3 mag.mounts, only cheaper. Arrives and is Hell for stout. Easy to pinch fingers if careless. But like most MFJ stuff, it is horrible inside.Coax is smaller than normal, 1 small gauge center conductor. Braid is wimpy and wispy,like baby hair. Get this, the center conductor is wrapped around a nut inside the non weatherproof hub. The flimsy braid is fanned out, at least PART, and trapped under a washer. Shameful. Change to Belden cable and add solder lugs. Fill the hub with weatherproof sealer
Only thing good is the magnets and the bracket.

If you're going to rate something you should at least buy it first. And use your call so people can email you with questions. I have 7'+ Iron Horse hamsticks on top of my Chevy Silverado with this magmount. This combination is 1-2 S-units stronger than my ATAS100 mounted at the back of my truck rail. Not one problem at all. It holds up to 80mph no problem and even stays when the antennas smack on low tree branches. (cough, cough even though the max speed limit in California is 70) If you go to the Tarheel website you will see several photos of this mount being used with the little Tarheel on top of trucks. After two years it still looks good and works good.

Not Good

I called them at MFJ and asked if it would hold a 102" steel whip on my mobile at 55 mph....It won't even hold it good enough at 40mph....It makes the recieve and transmit break up....They might be good for a 2ft-4ft antenna but surely no 7-8ft....
