The radio can't be 500mw when they use 5db gain antenna..it would put them far over the 1watt limit. It is likely closer to 250mw but the actual output power varies a lot depending on the radio encoding used and the channels. Some are more and some are less. It is not legal to do what you propose but it does not appear the FCC does much enforcement of the law.

It likely uses the standard rp-sma connector....the exact connector they invented to make it harder to use after market antenna.

Be careful to use the shortest cable you can and use the best quality microwave cable you can afford. Although not extremely expensive the cost of this cable is part of the reason you see bridge devices with all the electronics built into the...
