[Today’s run: Watson Road\u00a0 3.5 miles]<\/p>\n

Today’s picture is of my overhead feedline run from the house to the tower.\u00a0 I have four 12′ 4×4 posts that I have buried about 40 inches in the ground.\u00a0 So each is just over 8 feet tall.\u00a0 I have ropes strung from post to post.\u00a0 I plan to use the posts to get my feedlines and rotator cable to the tower base.<\/p>\n

I am still contemplating how to handle grounding.\u00a0 I would like to have a good ground system at the tower base then just use disconnects on the shack end.\u00a0 Right now I only have one lightning suppressor.\u00a0 So I guess I will put a bit of slack in at that last post and later put in some lightning suppression devices there.<\/p>\n

Also, for the rotator cable I am using a run of larger wire between the house and the tower base followed by regular 8 conductor cable up the tower.\u00a0 So I will have a couple of 8-port binding posts on the first pole and the last pole to transition between the two types of wire.<\/p>\n

I need a container for these things on the first and last posts.\u00a0 I hope to find a rubbermaid type container that will do the job.\u00a0 It may not be completely waterproof after I poke entry\/exit holes in it.\u00a0 But it will keep most of the rain off.\u00a0 And if I get something clear I can check it out without much fuss.<\/p>\n

I am imagining I will have three RF feedlines:\u00a0 1 for VHF beam, 1 for HF beam, 1 for HF wire antenna (dipole or G5RV).\u00a0 I have plenty of the smaller coax cable (rg58).\u00a0 I have about 50 feet of LMR-400, and I have 200 feet of nice new stuff which is my best shot for the VHF application.<\/p>\n

So (thinking out loud here)\u00a0 I need the new cable to come down from near the rotator to the tower base, have a bit of slack for future lightning arrestor, etc, then go across the yard to the shack entrance, have another bit of slack, then to the entry panel.<\/p>\n
