Introduction
The NanoVNA is a very compact and useful instrument that can be used to test a variety of antennas (Ref.1/8). So far I have tested most of my antennas with the exception of a few whip antennas that are used with the RTL-SDR. In this post I am testing a compact VHF (136-174MHz)/UHF(400-470MHz) antenna. It is approx 30cm long with 2 coils. It comes with a magnetic mounting base and coax cable with sma connector (Fig.1).
SWR 100MHz – 600MHz
Figure 2 & 3 show the sweep results for SWR showing the pass bands for VHF & UHF.
