Preamp clears off-air picture Finally had it with a fuzzy TV picture from your off-air antenna? Time for the mast-mounted preamplifier. A must if you live farther than 30 miles from a transmitter or if you have a 50+ ft. cable run, this high-performance signal booster eliminates screen fuzz. Requires 300 Ohm flat wire for the connection between your antenna and the unit; add coax cable from the preamp to your set.
