Preamps covers the amplifiers installers mount at or near an over-the-air antenna to boost weak signals before they travel down the coax. Bursma Electronic Distributing supplies antenna preamplifier wholesale orders to dealers and installers, with high gain models, a dual UHF/VHF unit, a two-input amplifier and the kit needed to connect an older 300 ohm antenna to a 75 ohm amplifier.

Antenna preamplifier wholesale: products in this category

BLOVAULTER3DUAL: a dual UHF/VHF preamp, model 5125.
BUA10G222: a high gain preamp.
CM17777: a high gain amplifier covering VHF, UHF and FM.
DITDT-RAMP20-2: an amplifier with two inputs.
WINLNA200: a preamp rated at 20dB on low VHF, 15dB on high VHF and 16.5dB on UHF.
WINAP1000: a 300 ohm antenna to 75 ohm amplifier kit with 4 feet of coax.

A preamp earns its place on long cable runs, on installs that split the signal to several TVs, and in fringe areas where the antenna alone cannot deliver enough signal. Match the bands the amplifier covers to the channels the customer wants, and use a two-input model where separate antennas need to be combined.

Antennas, masts and coax for the rest of the install are in the Antenna - Tower - Satellite division. For pricing and availability, dealers ask their Bursma sales representative; to order, open a dealer account.
