    I am not understanding why most if not all the radio manufacturers are going to sma. I like to bnc connections better on a handheld radio. I am noticing the even the scanner marker has been making their radios with sma also.
    With the bnc you can change antennas quicker and in the mobile you can hook up a mobile antenna with ease. I feel the bnc is more sturdy, more durable, and can withstand a drop better than sma.
    Your thoughts??

    I vote BNC!!!

    I don't like the SMA either, especially if I want to change the connection often. My guess is it is cheaper, and smaller. Not hard to use an adaptor tho.

    They want you to have to buy the SMA cables and such since must don't have the tools to make their own. BNC goes way back to token ring networks and pro video just like XLR's in audio.

    I prefer BNC as well, but I can understand the use of SMA with HTs that are getting smaller and smaller.

    Too much wear on an SMA They were never meant for frequent disconnects and reconnects.

    As a manufacturer of products that uses SMA connector on the items, I can attest that they are MOST FREQUENTLY broken off! I see transmitters returned almost daily with SMAs gone. BNCs are MUCH more robust. On the other hand, BNCs are as good to use at 2.4 GHZ as SMAs, which is why we use SMAs. N connectors are just too large for the small transmitters we make, so SMA is the only choice. Users just need to be GENTLE and not let GORRILAs use them!

    I also prefer the speed of bnc. My guess is manufacturers see sma as smaller and is more water resistant/waterproof for milspec? Wait, that doesn't make sense. A milspec rating should mean the connector is robust.

    I was thinking between Yaesu and ICOM handheld for 2 mtr mono band radio. I choose ICOM IC-V80 , because it has BNC connector. I usually prefer Yaesu Radio , but I made exception on this one. Size of the radio does not matter to me that much, I prefer handheld with AA battery capable, and BNC connector.

    There are some good SMA-to-BNC adapters out there, with rubber grommeting to take the stress of the antenna connecting/disconnecting.

    This is the one I used with the VX-5R when I had it - will probably buy another if I get a TH-F6A: http://www.wa3hrl.com/smabnc/
