Tram200-Watt Pretuned 400 MHz to 495 MHz UHF Fiberglass Base Antenna with 50-Ohm UHF SO-239 Connector, 39 in. Tall, Stainless Steel

This is a good performing little antenna, but heed the directions in that it MUST be tuned to your frequency. The wire elements slide out from the fiberglass tube and are cut to lengths based on a chart. I cut to a lower frequency on the chart and tested with an analyzer, the chart was very close so then I cut to my final frequency. About 10MHz bandwidth is all you should expect, this will not cover amateur 70cm and GMRS very well. If you are experimental and going to use this for a repeater or something it should be able to be cut for downtilt.

Pretty good antenna. Was expecting something cheap. But is made pretty good for what it is. Antenna tuned really nicely after cutting a hair more off then the cut chart had me but it got me in the ball park. 1.00 swr I have nothing to complain about.

Here is what i've discovered about this antenna. Unit must be "cut" to your desired bandwidth, however IF you plan on running any POWER through your repeater do NOT trust the chart !!! If you are only running 4-8 watts MAX through your "handheld" unit attached to it.... it is "somewhat" accurate for cuts. Having followed others advice and starting LOWER than intended frequency it tunes fairly well with LOW power. Pushing 4 watts into it and using a starting cut of 458Mhz the SWR was very acceptable. 1.02 throughout the 462mhz band.... 1.08 on 465Mhz and 1.2 on 467Mhz. The moment you add POWER your readings will jump. At (30 watts) in I got 1.5 on 462Mhz band, 1.7 on 465Mhz and 1.99 on 467Mhz. While these readings are "acceptable" my repeater will be running (50 watts) and i'm sure the reading will increase further. Once POWER is applied the antenna also becomes VERY "narrow" banded.My suggestion is to start cuts around 452Mhz WITH power applied and SLOWLY move up. I had to stop at 462Mhz to get the readings I first told you with (30 watts) applied due to "increasing" SWR.

Unless your application requires your antenna be very remote or otherwise inconvenient to get to, this antenna is a great value. It is well built and is totally suitable for many applications where the "hardened" much more expensive commercial antennas costing hundreds of dollars are not required. It performs as advertised. One caution: This antenna requires precision cutting to frequency, and a cutting chart is supplied with the antenna. Make your first cut considerably lower in frequency than your target frequency, measure forward and reflected power, then shorten the elements in small increments until the antenna tuned frequency comes up to your target frequency. Don't just rely on the cutting chart, as it is very possible the result would be an antenna tuned above your target frequency.For example, my target frequency was 463 MHz. I cut the elements to the lengths specified for 452 MHz, and the antenna was actually tuned to 457 MHz. I made 2 more cuts, one at a time, then measured the results. Shortening each element by a total of 6 mm each from the first cut brought the antenna tuning to my target frequency of 463 MHz. Had I just used the chart and cut for 462, the tuning would be well above my target and no way to go back down because you can't add back the required element length.This antenna is an incredible value for many, if not most applications, and worth the effort to tune it correctly.

I have no problem cutting this Antenna because I've learned from my past mistakes. It would be better if they had instructions on how to install this and actually cut it for the right frequencies. Before this, I had an Ed Fong Antenna. The Ed Fong Antenna is a great Antenna but this helps with the areas I've never reached before. I get 20 miles from radio to radio and easily hit three different repeaters on GMRS. I would love to see Tram make an Antenna that doesn't need tuning to help people who don't want to cut the Antenna. This Antenna is well built and should last for many years.

junk made cheap not tunable at all this model i wasted my money on thisthen when i took it down were the fiberglass mounts into load area was falling apart swr right out of the box 5.9 at 462 600

The instructions leave something to ve desired but it's simple enough to figure out.

Got this to match up with my Midland MXT500 setup as a base. It was easy to trim the elements for use for my GMRS system, I have it on an 80' tower with the top at 85' coupled with LMR 400, It reaches out about 32 miles to the north 22 miles north east and east and around 12 to the west and south do to terrain. Overall for the cash it was well worth the money.
