Hi That’s likely a “better” antenna for a TBolt-only setup than the L1 / L2 gizmo that we have been chatting about. Why? 1) if it’s still $25 it would be ~ 1/4 the price 2) it has a pretty good filter built into it. 3) it’s designed for continuous outdoor use (connector is well shielded etc) 4) It’s smaller and easier to mount Lots to like.

Generally speaking, you can seal most RF connectors quite nicely with a few layers of self-amalgamating tape and a layer of PVC tape over the top of that (to protect from UV). Practically speaking, if the antenna is mounted on the top of a pole, >95% of the rainwater is going to run down the side of the antenna and drip off the edge (assuming something shaped roughly like a PCTel 26dB timing antenna). The seals are more use if the antenna is mounted on a flat surface. -- Phil. lists@philpem.me.uk http://www.philpem.me.uk/
