That spider is now in the far back of the yard, there wasn't any place in the garden to leave her when I was clearing plants, so she traveled on a big chunk of okra root and stem to the wooded part of the yard.

I got out the tall ladder and climbed up to remove the the antenna head from where it was dangling on the coaxial cable. Instead of waiting for the roofer to come and struggle with installing it on the old spot (edge of the roof) I went to the attic and attached it inside in the same general area. Since it is on the truss it didn't need much reinforcement to keep it in place, and since the last antenna already had an amplifier I didn't even have to put the new one on, it is plugged into the old one. Works fine.

I did two things before setup: I located the broadcast towers on a map and used Google Earth to draw a compass line between the house and the towers (109^o) then got my old Silva Ranger compass (used for forestry work and mountaineering) and set the declination for this part of North Texas (+ 3 ^o - it was about + 18 ^o in the place I used to work and climb). (More info) I was then able to point the antenna to get the best coverage. Works perfectly. Everything I was wearing goes into the laundry now, there's a lot of dust up there.
