1000.4 WA DISH antenna's are actually obsolete. We currently only use 1000.2 WA DISH antennas for new WA installations/upgrades.
For EA we use the 1000.4 EA DISH antennas for new installations/upgrades.
That's too bad because DISH's 1K.4 WA Dish(which is a larger reflector) gives higher signal readings(10 points higher).
Guess the next step up(for more signal because of too much rainfade) from the 1K.2 WA would be the 500+ or 1000+ for the WA?.
