Hi Steve, First, avoid using LMR-400 for duplex use. This and 9913 are not good for duplex. Aluminum shield and tinned copper braid rubbing together and setting up corrosion causing noise. This is not a very long run, try and get some 1/2" hardline, you will not be disappointed. Spend all you can on antenna and feedline.
Take a look at the Hustler G6-270R antenna. Short and one piece, you only need to install the radials. (Use No-OX on the bolts that holed them in when building.) Low angle of radiation, built pretty solid. N connector. And the bonus is you can add a Diplexer in the repeater cabinet to add a 440 control receiver. I have this setup at 150' on a cell tower and it has unbelievable coverage. I have had a G7-144 in the air for almost 20 years, no problem. Top mounted at 71' to the tip. The G6-144 has less sturdy radials and a little less gain. They both will last a long time but figure on replacing ANY fiberglass antenna 15-20 years down the road even if it don't get a direct hit. The fiberglass just weathers out. Not to mention some of them suffer broken connections internally. Oh, by the way all of the Hustler antennas mentioned are DC shorted so less likely to take a hit if grounded properly. The Diamond and Comet antennas will probably only last one or two seasons in your weather! I could write two pages of faults in construction on these brands. Just not build sturdy enough. They don't last long here in Michigan. I am in the Detroit area.
