Does it need tuning after installation?

No. It is pre-tuned, so it mounts on an NMO base and is ready to use without cutting the whip.

What mount does it use?

It uses a standard NMO mount. The mount itself is not included, so you need an NMO base on the vehicle or a magnetic NMO base.

Which bands does it cover?

It is a tri-band antenna aimed at 2m, 70cm and a third band for mobile radio. Check the exact band split against your radio before buying.

How much power can it handle?

It is rated for 100 watts, which covers most mobile radios at full output.

Is it good for a scanner?

Yes, it works for receive-only scanning across its bands, though a dedicated scanner antenna may hear more on distant signals.

It is 17.5 inches tall and weighs 0.4 lb, so it stays clear of most low clearances.

Our take on the Tram 150 Tri-Band NMO Wideband Antenna

The Tram 150 is a 17.5-inch tri-band mobile antenna with an NMO base, 4.12 dBi gain and a 100-watt power rating. It comes pre-tuned, so it mounts on an NMO base and goes on the vehicle without cutting or adjusting the whip. It suits hams and scanner listeners who want one short antenna covering 2m, 70cm and a third band instead of swapping whips. Against single-band NMO whips it trades some gain on any one band for coverage of several, and its short length keeps it clear of garages and drive-throughs.

Best forMobile and in-vehicle radio useHams wanting one antenna for several bandsScanner and monitoring setupsDrivers who need a short, low-profile whip

Pros

Pre-tuned, so no cutting or tuning on install
Standard NMO base fits common mounts
Short 17.5-inch whip clears low garages and car washes
Handles up to 100 watts
Light at 0.4 lb, so little strain on the mount

Cons

Gain is modest at 4.12 dBi, less than a dedicated single-band whip
Tri-band coverage means narrower bandwidth per band
Needs a separate NMO mount, sold on its own
Short whip can be a compromise on weak fringe signals

What reviewers say

Owners of Tram NMO antennas generally report solid build and easy installation, and the pre-tuned design is a common point of praise. Some note that a short tri-band whip gives up range compared with a taller single-band antenna.

What people mention

BuildPraisedOwners describe the whip and base as sturdy enough for everyday mobile use.
SetupPraisedThe pre-tuned design means it goes on an NMO mount without cutting or adjusting.
RangeMixedSome find the short whip gives up reach on fringe signals compared with a taller antenna.
BandsMixedCovering several bands is convenient, but bandwidth on each band is narrower than a dedicated whip.
