I am about to install a 6BTV at the bottom of my back yard in an area with trees (not deeply forested), and I thought to sense check my approach with the vast experience of the ham community. One constraint I have is that I want it to be pretty much invisible to my neighbors on either side (nobody is behind us) and I have found just the right spot: an oak tree around 60 feet high blocks it perfectly from the neighbor of main concern. It is about 9 feet from that oak tree and about the same distance from another of similar size. A third oak is a bit farther away, forming a triangle with the vertical inside the triangle. I also plan to paint it with camouflage colors. The clay soil is very hard, so I will pick up a post hold digger and just put in however many hours are necessary to get down 4 feet. I'll pick up a reciprocating saw to get through any roots down there, and a digging bar to pry rocks loose. Then I will have my beautiful assistant (the XYL) hold the 5-6 foot steel pipe in place while I pour in the concrete. I am a complete beginner with concrete, but there is a type called Post Crete that is pretty convenient: you fill the hole 1/3 with water and keep dumping bags of the dry mixture in until there is powder sitting on top. It sets in 10 minutes so I will need to have the magnetic level ready. It is apparently based on Portland cement. The radial situation is an unusual one: in this part of the back yard (where little would grow beneath the oaks) I had put down fairly thick black plastic and bark chips on top. My plan here is to sweep the bark chips away temporarily, hose down and dry off the plastic, lay 30 16 foot radials down (maybe #18 gauge stranded insulated wire) and first use lawn staples to hold them down, but also use black duct tape at frequent intervals, which should stick to the black plastic. I don't want little loops popping up that could create a trip hazard. I may pick up the nice DX Engineering radial plate, SO-239 thing and tilt-over mechanism as well. Once the antenna is installed, I use a RigExpert to get it resonant where I want it. Then I do a run of coax to the shack without burying it, drill through a cinder block and brick wall about a foot thick at an angle sloping downwards to the outdoors, push the coax through the hole and check that all is well from the shack end (about 200 feet of Messi and Paoloni later). Then I go back to the vertical, cut a long slit in the plastic directed towards the house, bury the (direct bury) coax in it, duct tape the slit shut, dig a slit/trench in the grass a couple inches deep, push the coax down and stomp the slit closed. The final run will actually be buried under gravel for about 30 feet or so, using lawn staples to keep the coax from popping up. Also some large heavy plant pots will be holding the coax down in this section. I will need to do something about lightning protection (I will read and learn). Ground rod near the shack entrance: right near this point is where the gas mains and the electrical mains enter the house. Not knowing the exact locations of pipes and cables makes me think slamming a ground rod down there would not be smart! I could easily connect some thick copper cable to the ground at the electrical junction box - not sure this is better than no ground rod though..? I could drill through an interior brick wall and connect thick copper cable/braid to the cold water mains... (I am in learning model here too). Not sure what is best here. The final stage is guying the 6BTV. We tend to have a season where we get gusts up to 70 mph once per year, so guying seems sensible. Given the vertical is in the middle of three 60 foot oak trees, I thought to use some dacron rope to guy them directly to the trees at a height of about 7 feet (avoids a trip hazard). I am ASS-uming that at a height of 7 feet, a 60 foot oak tree doesn't move around a lot, even in 70 mph winds. I wonder if there is data on this? (Maybe one of the cords should be a thick bungee cord for flexibility?) And I thought to attach the guys to the 6BTV somewhere around half way up. One thing to note: in the UK an antenna installation is considered a "building" and needs full planning permission! This is the reason for going the "hidden vertical" route... OK people - I am all ears! What am I about to do wrong, and what can I do that's smarter?
