Antenna analyzer
The SARK-110 Antenna Analyser is a pocket size instrument providing fast and accurate measurement of the vector impedance, VSWR, vector reflection coefficient, return loss, and R-L-C (as series or parallel equivalent circuits).
Typical applications include checking and tuning antennas, impedance matching, component test, cable fault location, measuring coaxial cable losses, and cutting coaxial cables to precise electrical lengths.
The SARK-110 features a Direct Digital Synthesis (DDS) generator with a range of 0.1 to 230 MHz and a frequency resolution of 1 Hz. The instrument has full vector measurement capability and accurately resolves the resistive, capacitive and inductive components of a load. The measurement reference plane is automatic adjusted via the Open/Short/Load calibration standard to enable the accurate impedance measurements at the end of an intermediate coaxial cable.
Price 330$ at Seedstudio
Don't know if it could be useful for the community but it maybe interesting for some guys.

Frequency range is only 200 MHz, so not of any use for FPV or telemetry. That's why it's only $330.

for those using the RF Explorer , anew module is out
RFEMWSUB3G is an Expansion Module for RF Explorer. It can be plugged in your RF Explorer unit to extend the coverage to 15-2700 MHz (0.015-2.7GHz) continuous frequency band.

The RF EXplorer and the SARK 110 are totally different the first is a spectrum analyzer and the second an antenna analyzer.

Similar product of my friend: https://sites.google.com/site/sp3swj/svna160 working to 180MHz, dedicated mainly for HAM radio.
