Hi there, Adam. I think that you can save some money by using unshielded gel-filled=20 cable (as opposed to shielded). The shielding is intended to protect=20 against external EMI and that simply is not normally a problem when=20 burying the cable in dirt. Using a conduit makes it easier should you either have to add to or=20 replace your wiring. You have to dig the trench only one time - this=20 is a *lot* easier on you should you change your mind about what you=20 want at the remote location. Use the largest conduit that you can afford. 3/4" would be the=20 minimum diameter that I would use but, depending on your future=20 plans, you may want to consider 1" pipe. I also assuming that you=20 would be using PVC conduit with glued joints. I normally dig my trenches to be about 24 inches deep and place a=20 pressure-treated 2x6 on top of the pipe (or cable) before re-filling=20 the trench. dwayne At 09:57 AM 5/7/2015, Adam Field wrote: >Hi guys, I'm doing a point-to-point radio link using a pair of PoE powered >5GHz ethernet bridges.
