It doesn't seem as robust as my old Larsen NMO.
I haven't used an 'Tram' antenna and quite frankly, seriously doubt if I ever will. Not exactly a 'hi-end' company, other than maybe for CB stuff, maybe. I have doubts about them and their claims for their antennas. Sorry.
I'll know more in the coming weeks.
Why bother fussing with a broken antenna when a "new" one comes along? The Tram is a perfect case in point.
I should throw out these "project antennas" or pass them on to the club. It sounds like the perfect project for any interested new amateur operators. They can get on the air cheaper and tinker with equipment at the same time. :laugh:
The Tram 1180 is a good antenna. About 37 inches tall, it covers both 2m and 70cm. The manufacturer claims 3dB on 2m and 6dB on 70cm. It is well built with a protective metal cap and a gasket sealed metal base ring. The best part is that it uses a gold plunger center pin contact, not those flaky silver leaf springs that corrode and loose their tension. Rated at 50 watts but will withstand greater power if the SWR is low. High SWR will produce enough heat to melt the phasing coil housing.(as reported on eHam.) Other antennas I have used from a well known manufacturer of gray base antennas have always developed a crack at the base of the matching coil and let in water and caused corrosion. The rubber sealed metal ring at the bottom of these antennas prevents that from happening.
TRAM-Browning is the old company that used to make CB radios. They have now branched out into antennas and other radio accessories. I've been running one of these on my Subaru Forrester and one on my motorhome for several years now with no problems.
Use a good NMO base adapter mount or a mag mount and it will make a great base or mobile antenna with gain.

I notice you don't have much good to say about anything if you think it is connected to cb somewhere along the line.
To the OP...I know this is late in the game, but this is one of the best antennas I have used yet for my 2 meter rig, and I wouldn't trade it for anything else. I was not a Tram man myself, but after trying this 1180 I'll buy another if anything happens to it.
Besides, this particular model # antenna holds some sort of world record for transmitting distance...
Tram 1180, Dual Band NMO Antenna, $35.00 ea. NOTE: This antenna set a Transmit Record of 715 Miles in a Earth/Balloon/Earth Transmit Record. "We are Proud to say that we were the Antenna Dealer that sold N5PAX "Bob" this Antenna"! Darryl, NX5W"
You can google this for more info also.

If not; then who?
I have no idea who does, I use a Diamond X200A for mine, an it serves the purpose well for what an where I talk.........
be going down the road and watch the glue come loose and the coil be bouncing all over the place
The damn thing works good for my little 65 watt yaesu radio an thats really all I give a crap about. I don't give a damn if anybody here buys one or not, no skin off my butt. I was just telling the op my opinion of'em from my experience.
I inquired about a 2m/70cm base antenna on this and other forums, then purchased the Jetstream JTB-1 for $85. I have no problem getting into repeaters 15/20 miles away with full quieting on 1-2.5 watts. If I increase power to 5 watts I get into repeaters (again with full quieting) up to 60 miles away. I have the same results on simplex. This is a no-tune antenna, and SWR is 1.2:1-1.4:1 across both bands. It's only been in the air for a few months so I can't comment on durability/longevity, but so far I am quite pleased with it's overall performance.
I have some uncomplimentary things to say about several 'ham' connected companies too. So, it has very little to do with 'CB' connected companies, although, there seem to be more of those 'uncomplimentary' type companies involved with 'CB' things than 'ham' things. Or, I really ought to say, that there used to be. That's changing now unfortunately. Several reasons for that 'change' I think, the most important of those reasons is a lack of knowledge. A natural result of 'dumbing-down' things to favor the 'least common denominator'. (If you think that is aimed at the 'CB' world, you've entirely missed it.)
