I can see that, thanks. And thanks, Eigenvector.

Satellite signals are in the 4 GHz range and can be blocked by thunderstorms
as well as trees, etc. Also, any upgrades to a dish will probably be to
either the software or possibly the feed horn, so the installation itself is
relatively permanent. Over a few years we've had a few feed elements
replaced, which isn't a big deal. --

Unfortunately that's not the case. I'm currently on my third dish
antenna from DirecTV, for instance. If there's a bright side, though,
the mounting hole pattern on the dishes does appear to stay the same.
Here's the scenario with my 3 dishes:

Dish 1 - Standard dish
Dish 2 - Upgrade to HDTV
Dish 3 - Upgrade to receive local HDTV channels and HDTV from new
satellite

Nope. Not through leaves.

They are, they are microwave. Easily absorbed by water for example.
The water in leaves is what makes the trees 'microwave opaque'. <g>

Uh huh! I get it now. That's what gets hot in microwave ovens too.
We got to get rid of all that water. It seems to cause a lot of
trouble. Aren't there old mines in Utah or Nevada where we could put
the stuff?
