I just recently installed the Dakota Alert DCPA 4K that uses the buried vehicle probe. The transmitter and receiver are located about 1/2 mile away however the transmitter is at the bottom of a hill and my alerts are spotty. Maybe 50/50 success rate at best. I know I can move it closer to the house however this is the preferred location due to being in a place in the drive that cars cannot go around it and also allows more time to alert us to incoming vehicles. In talking to Dakota support they cannot make recommendations due to FCC limitations. I know about zero as far as radio.
It looks like both the transmitter and receiver uses a helical internal 433 MHz antenna. The receiver antenna is about half the size of the transmitter antenna. Each antenna is soldered to the board and would be fairly easy to solder in a different antenna. Pics of each attached. Although both antennas are internal it would be easy to modify the housings if needed for an external antenna. So...............
What recommendations can you give me? Add a better external antenna to the receiver, transmitter, or both? And what antenna would you recommend? Because I am getting some alerts I don't think I need a huge bump in signal. Appreciate any help.
