I started the installation of my antenna at the new house this weekend. A kind member of the DFW Contest group gave me a GAP Titan DX vertical for the great price of free. (as payment, I gave away my fiberglass mast kit to another local ham!) The antenna isn't in the best of shape, at least one of the elements is in serious need of repair and the coax was pretty roached at the connector end. Oh well, free is free!
I started out by digging the hole for the mast, and quickly learned what this "Texas soil" was all about. I knew it was full of clay, but I did not expect this! Basically 4 inches down, the earth turns unto black tar. The clay is thick, heavy and it sticks to everything. I spent as much time digging as I did cleaning my tools. None the less, I got a hole big enough and deep enough to plant the mast in, albeit a little shallower than the instructions call for. Filled it up with 4 bags of concrete and that's curing at the moment. The initial idea was to bury a section of pipe that the mast could slide into but I couldn't find anything the appropriate inner diameter so I just said to hell with it and used the mast as is. This will put the bottom of the antenna at about 6.5'. It'll be interesting to see how difficult it will be to put the antenna on it. At 25' long and 25 lbs heavy, it can be a bit unwieldy once its vertical.
Sunday, I decided, would be the day of no return; I would cut a hole in the wall of the house. I'm sure we've all been there, trying to decide exactly how we'd go about getting coax into our homes. I decided this time I'd "do it right." I got a really nice aluminum NEMA enclosure on eBay for a song and I was very surprised to see it when it got in, it was way bigger than expected! Yes, there were measurements but you don't know what 12" really looks like until you see it in person.
If you don't know, many of the homes in Texas are built with brick exteriors. I don't know about in the past, but these newer homes are actually built with a brick facade. That is to say that there is an air gap between the outside of the structure and the inside of the brick, and the brick merely floats out on its own, cosmetically. What this means practically, is that the wall from interior to exterior face, is nearly 8 inches thick! Naturally my 2" masonry hole saw was not going to be long enough, by about the thickness of a brick. I had to figure out where I was inside and translate that to the outside, so I could drill from there. It took a bit of trial and error trying to break through from the inside with a very long screw driver until I figured out a way to get pretty close by measuring from my window frame to my hole. I could see I was drilling into a T intersection in the brick about 27" from the window, so all I had to do was find that area, poke a hole from outside to see and sure enough, I hit it dead on center.
All was not as well as it could have been though. The hole saw I bought was not really doing much good with my standard rotary drill so I quickly gave up on that idea and went the brute force direction: drill a bunch of small holes and chisel away until you have a hole big enough to fit the 1.5" PVC pipe. This made quick (and quiet) work of the job and I was through the brick in no time. I quickly drilled out the holes for the mounting screws for the NEMA box and bam, I was pretty much done with that. A little expanding foam stuff and some caulk was all I needed to finish up the job.
I'll have to add a little paint to the opening on the inside and you won't even notice the hole probably. I'll also have to fashion a piece of foam that'll plug the hole up nicely. I'm ready to get back on HF though, I can tell you that!
