I have been using the Minikits EME141 relay kits for both VHF and UHF for a long time but I never did any measurements. Using the NanoVNA I now have done a sweep for HF, VHF and UHF.
HF is excellent, VHF and UHF are very good. See image below (click for large image). Note that the SMA connectors during measurement can add some losses. Insertion loss is -0.76dB at 435 MHz.
The EME144 is now replaced by even better releays.
