I had previously commented on the how most of the handheld radios are adopting SMA connectors instead of BNC connectors. See Say Goodbye to the BNC. For example, the Yaesu FT-60 uses a female SMA connector for the antenna connection. I’d say this is the standard approach for the amateur radio market.
A few manufacturers have decided to use the male SMA connector as the antenna connection for their handheld radios. I suspect that these manufacturers are following the lead of commercial manufacturers (e.g., Motorola) who use the male connector.
Many hams will want to adapt these SMA connectors back to the good old BNC, to connect to existing BNC connectors or HT antennas. I had commented that these adapters are mechanically weak but recently I have come across some more sturdy adapters.
The adapter in the center is the common adapter for cable use but arguably mechanically weak for adapting HT antennas. The adapter on the left adapts BNC antennas to an HT with a male SMA connector. The adapter fits snugly on the top of the HT and provides mechanical support. Similarly, the adapter on the right adapts BNC antennas to an HT with a female SMA connector.
I have just started to use these more capable adapters so I am not sure how reliable they are in regular use. In any case, it makes sense to be careful to minimize the strain on any radio connector.
