CAMI® broadband isocouplers enable colocation of FM and TV on AM towers!


How To Add TV/FM Translators, LPFM and LPTV to AM Towers? Next Generation CAMI® Isocouplers!

The TV spectrum auction is over and the TV Repack has begun! Thousands of low power TV and TV translators that were displaced to free up auctioned spectrum will need to relocate or go off the air.

The Federal Communications Commission has also granted large numbers of FM translators for use by AM stations and new low power FM licenses, and AM translator rule changes are causing new applications to flood into the FCC.

These new licensees will all need antenna space, but many traditional TV and FM tower locations are under great stress due to the repack of almost 1000 full power TV stations. Many cell towers are capacity constrained, too expensive, or technologically limited to cell carriers only. Where can the new licensees go? AM towers!

AM broadcasters: Are you missing income opportunities? Find the gold in AM tower steel! You can open an opportunity to generate a new revenue stream. It’s a win – win for both AM station owners and translator/low power owners.

Many lower-power FM and TV stations can now place their antennas on thousands of AM broadcast towers using one of the five new, economical, and rugged LBA Technology CAMI® Broadband AM Isocouplers.

CAMI® Isocouplers were winners of the prestigious TV and Radio Technology Innovation Awards for 2016!
