There is a lot of confusion on low beam zip codes. I'm going to attempt to explain it.
129° Low Beam ZIP Codes refers to certain ZIP codes for which HD or SD Eligible Local Networks broadcast from the 129° orbital location have low signal strength and require the installation of 2 DISH 500 antennas for proper reception.
Part of the problem is, there are many Alaska (probably all) zip codes that are considered low beam in addition to the many mainland dma's. However there is 1 big difference in Alaska. They use a Dish 500AK for 119 and 129, it's a larger dish than a regular 500. It cannot use a twin lnb because of its larger size and requires an external switch. Depending on their package and location they may require a wing for 110. All customers in Alaska get a Dish 500AK, which begs the question. Why consider them a low beam to begin with?

At this time the Hopper 3 can only work with a dph lnb designed for the 1000.2 dish on either western or eastern arc. The dph lnb has 1 input, this puts a lot of configuration options for low beam customers, international and those with locals on 77.
Options are definitely there. The big question is, will dish allow it? Some are reporting yes and others no.
