This one is the Good One. Shielded for unwanted emissions, easy to mount an SMC connector and 433 MHz antenns’a @ $2.00 – $4.00 make the best possible use of the +20 DBM (100 mW of power). With the antenns’a away from city noise and mounted about 5 feet in the air vertically the radios ‘should’ be capable of 2 km or more I’ve measured 2.3 km (about 1.5 Mi).
