Nice unit. I do not care for the hose clamp arrangement mount to mast would much prefer the u-bolt type mount. However it works well . Very easy to assemble. Would buy again.

Many reviews complain about missing hex head (called Allen head by us old timers). That was NOT the case for me. All four screws were in the NMO base and tightened down nicely on the radials. They are in there fairly deep, so I just used the provided Allen wrench to back them out a little to be sure. I know things can go wrong, but in my case, everything was there, nothing loose in the bag(s) and it works as described.

I ordered this item and it was missing the set screws so I exchanged it for a 2nd one. The second one had 3 set screws and 1 radial, so I asked what I should do and they said return it and will make sure set screws are installed. Now I received the 3rd one 4 months later. It has 1 screw. I'm going to try Lowe's or Home Depot and see if they have any set screws. Obviously tram doesn't care about their customers and sending out a quality product. The only reason I kept exchanging items is because they refused to refund my money. They only would agree to an exchange but even with the exchange parts are always missing. I recommend never buying anything from tram because I've had the same issue with their antennas. I wish comet had this item because I usually buy comet exclusively and have for years. Buyer be aware of get screwed...

I have used many of these for amateur and land/mobile radio. The perfect way to take a mobile antenna and use it Fox fixed use.Some of those have been up for 25+ years trouble free.Use dielectric silicone grease on the threads of the MMO mount, center pin and PL 259 threads and you will have an inexpensive trouble free installation for years to come.Always seal the coax connector with tape or use coax seal. Water infiltration is your enemy.

Lo uso con una Tram 1126-B (1/4 de onda) para un equipo UHF (recorté y doblé a 45° los radiales para obtener una ROE 1:1).La base se ve que durará muchos años, y los rádiales tiene una magnífica consistencia (suficientemente rígidos para mantener su forma).Si tuviese que encontrar algún inconveniente, este sería que la pieza donde se colocan los rádiales no tiene un ajuste para colocarlos en la dirección deseada, sino que entra “a tope”, por lo que podrían quedar apuntando a un lugar distinto al deseado (que a lo sumo sería un problema estético).

This is a simple ground plane kit. It is optimized for VHF and higher frequencies.As far as the set screws go, I only saw two of them when I opened the package. Uh oh. Turns out, the two missing ones was inside the holes that already had set screws in them. The holes are deep enough that you can screw in two set screws and not realize it. So, check all four holes for set screws before complaining to the manager.So, if your intentions are to use this on frequencies lower than VHF, this is not the item for you. 2 meters, 220 MHz, 440 and up, you will do fine. For bands higher than VHF/2 Meters, you shouldn't need to trim the ground plane radials. I mean, if you put your UHF NMO antenna on your car roof, do you trim your car roof to 6 inches ? No. You can always have more ground plane than you need, but not less.I can't attest to the weatherproofness of this kit. I am using mine for attic use. If it were outside, I would pay attention to the base. You may need to seal everything up. Around the connector, at the bottom of the NMO base...etc.So far, this kit has met my expectations and I am quite happy with it.

Works as it should. The radicals are very flimsy or “light”. I was expecting heavier duty rods for the radials. Otherwise the unit is fine.

I bought this to be able to set it up as a base station antenna. This is utterly fabulous. I already have a 5/8 wave nmo magnetic mount antenna which I have taken off of the Mag Mount and have re purposed onto the Base Kit. Works very well. The 5/8 wave antenna now has a better SWR and had made me very happy. Good Kit!

Works well with the mag mount whip. May consider buying another unit to build an additional 1/4 wave ground plain antenna

I bought this kit, loved it, and immediately bought two more.Strangely, though, while the first one I ordered came with the SO-239 as pictured, the next two each came with an "N" connector instead. It turns out that for me this eliminates an adapter, so I'm thrilled actually. N connectors are better anyway, particularly in the UHF and higher bands, so I hope the next one I order comes with N connectors too. But you might not have wanted that. My suggestion is to just be prepared to put a different connector on one end of your cable if need be. It's still a great mount kit.Anyway, here's why I think these things are great. You don't have to use the ground plane at all if you don't want to, and then it becomes just a great NMO pole mount. The wire elements are all trimmable, but you should use serious dikes -- I got these just for the purpose [ http://amzn.com/B000PRWJ52 ]. They're long enough to tune for anything from VHF (1/4λ) on up, with as much precision as you can manage, anyway. I've got it down to about 1.065 VSWR so far for 1/4 wave UHF. This antenna [ http://amzn.com/B00438SJQC ] turns out made of the same stuff and so becomes an identical fifth element up top just like tuned 1/4 wave ground plane antennas are supposed to have, I guess.So please, TRAM, keep the N connectors! Or sell both, but make them unique products! Please!Regardless of the connector confusion, I'm giving 5 stars because this thing rocks and I wouldn't steer anyone away from it. Just be aware you might need to put a different end on your cable on one side. (Or use an adapter -- if you must)
