Introduction
The Nagoya UT-72G is the
newest addition to the Nagoya family of Mobile antennas.
The 72G was introduced for those wanting to use GMRS as
their primary band. The sweeps below show that
although this antenna was designed specifically for
GMRS, it also performs well on commercial and ham
frequencies as well. Also,
it's power capability is rated at rating is 80W.
What's in the Package
- Heavy Duty magnetic Base with 13'
(4.0m)
RG58A/U (PL-259)
- Main antenna element
- Coil Spring base
- 10" (26 cm) RG-316 Cable
to Handheld jumper (SO-239 to SMA-F)
- SMA Male to SMA Male adapter
Opening the package, you will find the hefty 3 3/8" x 3/8"
(8.5 x 1.0 cm) rare earth magnet at the base
with a rubberized pad on the bottom to prevent any
scratching of the paint. Driving down the highway with
the UT-72G attached to the roof of your vehicle,
this antenna is definitely not going to move.
The total antenna length is 20.5"
(52 cm) long with an
active element is 19"
(48 cm) long and just
over 1/16" (2 mm) thick.
A Nice Plus - 2 for 1
The cable is now 13' (4.0m) run of RG-58A/U terminated with a PL-259 connector.
Unlike some antennas using RG-174, the heavier cable has
lower loss and is resistant to pinching, crimping and weather
impact.
Also included is a 10" RG-316 jumper with
SO-239 and SMA-F connectors. While the main cable will mate with virtually all mobile
transceivers, the 10" adapter jumper with the
SMA-F allows the flexibility of easily connecting to a
handheld.
Also included is am SMA Male to SMA Male adapter.
Test Results
The antenna is omni-directional and rated at 3.5 dBi
gain.
For testing purposes, I placed the antenna in the center
of the roof with over two foot of metal in all
directions. The SWR results were excellent with
the target being the GMRS frequencies. The sweeps
below show that the SWR on both Tx and Rx were close
to 1.5:1 at the center of the GMRS band.
462MHz
468MHz

The coil at the base if the antenna serves a dual
purpose. Along with the flexibility of the antenna,
it also adds to its resonant bandwidth. This allows
an excellent match for both the 2m and 70cm ham
bands as well.
Antenna sweeps show good for both Ham and GMRS bands.
144MHz
444MHz

An SWR of less than 2.0:1 is obtainable between
138-168MHz and 420-468MHz. This would make it feasible
for use as a commercial band antenna as well.
Summary
Over the air test results were excellent. The antenna is commercial quality and will
not disappoint.
Good job,
Nagoya.
I definitely give it a 5 star rating.
