I'd use an F11 style cable, with flooding compound, for that distance.


A couple of rodent bites and a good rain and its all wasted and ready for the trash or several short sections to be salvaged.

Thats exacly what happened to 750', 250' and 200' runs of RG-11 flooded to me during Phase 1 of the Beverage system 22 years ago. It took less than a year.

After replacing with 1/2" CATV hardline life has been good since then. It was one of many partial reels left over when cable came to town. These days its found during a major upgrade or for storm repairs. The contractors rarely take leftovers to the next job as they are gypsys traveling all over the country.


With the rapid decline of the 2 way FM radio business 1/2" and 7/8" 50 Ohm hardline is a drug on the market and only worth scrap value. Its often free if you remove it but 900' will require some inline adaptors
