Separate UHF And VHF Amplification, Not One Blanket Boost

Separate UHF And VHF Amplification, Not One Blanket Boost

Many signal amplifiers apply a single uniform gain across all frequencies, which can over-amplify some channels while under-serving others. This RCA preamp uses separate UHF and VHF amplification circuits, each tuned to its own documented gain level.

Distinct gain figures for UHF and VHF bands

The amplifier delivers 16dB gain on VHF and 22dB gain on UHF through separate amplification circuits — specific, documented figures for each frequency band rather than a single blanket "signal boost" claim.

Extremely Low Noise (ELN) circuitry

The preamp uses ELN circuitry specifically designed to preserve signal purity and minimize interference — a named technical approach rather than a vague "clear signal" promise.

A switchable FM trap to prevent interference

A built-in switchable FM trap can be activated specifically to block interference from nearby FM radio frequencies — a targeted, optional feature rather than a fixed filter that can't be adjusted for different reception environments.

No outdoor electrical wiring required

Power is delivered to the outdoor-mounted amplifier through the coaxial cable itself via an included indoor power injector — meaning only a coax connection needs to run outside, with no separate electrical wiring to the antenna location.

Built specifically for digital signals, not legacy analog

The preamplifier is engineered to outperform older preamps originally designed for analog broadcasts, optimizing specifically for modern digital signal amplification — a deliberate design distinction rather than older analog-era hardware repurposed for digital use.

Documented intermodulation performance

The unit specifies an average intermodulation rating greater than 60dB — a concrete technical specification that speaks to how cleanly the amplifier handles multiple simultaneous signals without distortion.

Compatible with any passive outdoor antenna and any TV

The preamp is designed to work with all TVs and passive outdoor antennas, rather than being restricted to a specific antenna brand or television model — broad compatibility rather than a closed, proprietary system.

At a Glance

Who It Suits

This preamplifier suits anyone struggling with weak over-the-air TV reception, particularly in areas with low signal strength or long coaxial cable runs through splitters and multiple TVs. Its separate UHF/VHF amplification and switchable FM trap also make it a practical choice for fine-tuning reception rather than relying on a single generic boost.
