Product Review Nagoya UT-72
Magnetic Mount Antenna Dual Band VHF/UHF
Ham/GMRS
PL-259 and SMA-F
John 'Miklor'
The Nagoya UT-72 is the
latest addition to the Nagoya family of Mobile antennas.
The new antenna features dual connectivity as well as
smooth results on both the Ham bands and GMRS. Also,
it's power rating is 75W.
What's in the Package
- Heavy Duty magnetic Base with 14'
(4.3m)
RG58A/U (PL-259)
- Main antenna element
- Coil Spring base with lock nut
- 10" (26 cm) RG-316 Cable
to Handheld jumper (SO-239 to SMA-F)
Opening the package, you will find the hefty 3 3/8" x 3/8"
(8.5 x 1.0 cm) 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-72 attached to the roof of your vehicle,
this antenna is definitely not going to move.
The total antenna length is 21.2"
(54 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 14' (4.3m) 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.
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 very impressive, with
an excellent smooth
match across the VHF/UHF spectrum, both Ham and GMRS.
(and yes, I hold both licenses)
The tightly wrapped coil spring serves two purposes. The
most obvious is the flexibility, however it also adds
thickness to the element. This contributes the the
antennas broadband matching.
Antenna sweeps show good for both Ham and GMRS.

Summary
The over the air test results were excellent. I have
used lesser bargain antennas, and you get what you pay
for. The antenna is commercial quality and will
not disappoint.
Good job,
Nagoya.
I definitely give it a 5 star rating.
