A comparison of two similar antennas, the Retevis RHD-771 and Diamond SRH-771.
We plot SWR graphs and Smith charts, and check the antennas' repeatability. We measure antenna efficiency at a specific frequency. We discuss the key parameters to consider when choosing an antenna.

Detailed technical specifications, a photo review, and graphs of the Diamond SRH771 antenna can be found on the Viva-Telecom website: https://viva-telecom.org/14361/diamon...
