Contact sensors issues

[tomp]

There are a lot of posts on this topic. Just run a search on Bridge Range. Here’s one. I have tried it and it does help. Also using a 2 amp power source seems to help. And-don’t put the bridge in a Pan Cam!

Antenna for bridge

i see most people that have modified the antennas for greater range have done so to the sensor and not the bridge. i’d like to lengthen the bridge antenna. has anyone done that yet?
