Handheld antenna, they come in so many sizes. We could guess bigger is better, but hey who wants a 50cm whopper on top of their 145 Mhz handy.
I thought it may be interesting to put a few on my RigExper analyser and see how they look on 145 Mhz.
Let’s start with the
NISSEI RH-9090 – around £40 (Haydon Communication)

FLEXIBLE RUBBER ANTENNA (SMA), SUPER GAINER.
- flexible rubber antenna (SMA)
- 40cm long
- super gainer, for the ultimate in gain
- TX: 2m / 70cm
- RX: 25MHz – 2GHz
- ideal for airband
Seems very wideband, and has a resonance on 145 MHz, good start.

Super Small Fake Diamond
- 144, 430 and 1200 MHz
- Wideband RX
Mostly useless, unable to find any freq between 50 and 220 MHz that these resonate on. Not even as good as a dummy load.,
Unable to find any use for these, but don’t take my word have a look at the plot.

FLEXIBLE RUBBER ANTENNA (SMA), SUPER GAINER.
- flexible rubber antenna (SMA)
- 18cm long

Not surprisingly it had a nice dip at 145 MHz and was the best of anything tested.
