Really Long Coax Run

[Tallman]

Maybe you should just rig up a repeater for yourself. transmit with low power to your tower of high power!

It is some near stuff. They are building DAS (distributed antenna systems) in stadiums and hotel natonionwide that the antennas are light being feed by fiber. Cool stuff , they turn RF into light through duplexers and a major fiber network. Helped build the largest one in the US at the super dome in LA. Wish I would have taken photos!!!!

pics would be sweet .
soooooo ... the velocity factor of fiber optic coax/feedline should be somewhere between 100 and 99.999 ?

It's fast as light!! Losses are very low, normally under .5db with a fiber tester. This is through the entire system. The technology is here, and there is more to come!! The days of pulling in long coax runs up the tower are now becoming a thing of the past. Good and bad!! Less work in the end, but less time to complete the job as well.

Times Microwave LMR-400, from MPD DIGITAL Company directly on the web This hobby can get expensive, but you want to do right and only once. Buy in bulk rolls to save money. "It Cost Money To Run With The Best" Sure you can do cheaper but will you get the same results "NO"

My first thought would be a long wire and balun. Is the hillsides on both sides clear of any other utilities?? If there are no obstructions, some light wire and a bow and arrow would give you coverage. Multiple wires could even be used, only two at a time, to get the coverage that works best. I use this method in the woods and directional arrays are possible. I use very fine wire, but a little heavier would be best for longer exposures.

.......he wants to run coax up the side of the hill for about 450 feet. .....

even with lmr-400 that's almost 1 s-unit (4-4 1/2 db) of signal loss on both tx and rx . about 1/3 of your tx power will reach the antenna .... the majority 2/3 of your tx power will be lost in the coax run .

soooo .... spend $500ish and lose contacts for less effort...
or
spend a quarter of that with more install effort for much less loss/more power reaching the antenna keeping most of the systems ERP .

[222DBFL]

He needs some LDF4-50a or similar. The larger the better. 7/8" coax would work as well. But at 450 ft. You are taking about a bit of money. Not going to be cheap that's for sure!!

get a starduster m400 mount it as high as possible next to home , and use lmr 400 coax . this antenna will
help him get out of valley better and no need for 450 feet of coax thats just insane
