Description
The Blonder Tongue BTY-UHF-BB is a professional quality UHF broadband antenna for CATV and MATV installation.
It is an 11 element multi-channel design for TV channels 14 to 83 with a 75 ohm output for coaxial cable.
The antenna is a dual boom log periodic type with high gain, flat response, good VSWR, high front-to-back ratio, narrow
beamwidth and low side lobes.
The mounting assembly, positioned at the rear, allows the antenna to be mounted directly on vertical tower members.
This feature maximizes signal reception qualities of the antenna by keeping elements clear of support structures.
It also eliminates the need for outriggers and masts.
The antenna is supplied with hardware for mounting either of two ways: attaching to a mast (or tower), or attaching to the front
of a BTY-LP-BB (#4874) VHF broadband antenna. The two antenna combination produces a single broadband U/V antenna
version for channels 2 through 83.
Features
• Hard drawn 6063-T6, heavy wall aluminum boom for added strength. Square boom design assures positive lock with
mass mounting bracket.
• High strength 6063-T6 round tubular aluminum elements.
• Elements are affixed to the aluminum boom with a 15/16” thick mounting clamp for optimum element alignment while
preventing rotation.
• Heavy-duty stainless steel bracket has serrated teeth for added grip to mast.
• Bracket accepts mast sizes from 3⁄4” to 2-1⁄2” outside diameter.
• Antenna is completely pre assembled, ready for mounting.
• The antenna carton is sized for convenient handling and economical UPS shipment.
