According to the e-mail Christopher S. Dunne received from Great Belize TV, this station is very low power:

Dear Chris:
We transmit at relatively low power: 500W on Channel 5 from Belize 
City, 500W on Ch. 2 from La Democracia, and 200W each from Melinda and 
Spanish Lookout on Ch. 13.  Ch. 7 transmits at 1K from Belize City.
