U20337 Used RadioShack 2M Power Amplifier 12V 30W Model: HTA20

U20337 Used RadioShack 2M Power Amplifier 12V 30W Model: HTA20

Overall Condition: Used, fair physical condition with noticeable surface dirt on the body, heatsink fins, and rear connectors from previous use and storage. Front power toggle switch, status LEDs, and label graphics remain fully legible. Wiring Note: The attached DC power lead does not have a terminal connector attached at the bare wire ends, though the leads remain securely connected to the main chassis.

The RadioShack HTA20 (Cat. No. 19-1120) is a compact 2-meter (144–148 MHz) VHF linear power amplifier equipped with an integrated receive pre-amplifier featuring a helical resonator. Built to boost low-power handheld transceivers (HTs) up to 30 Watts RF output power, it runs on standard 12V–13.8V DC negative-ground power supplies.

Accepting drive levels between 0.5 and 5 Watts, the unit features automatic RF-sensing transmit switching, making it an ideal choice for mobile setup or bench station work once proper DC power connectors are terminated.

Condition Breakdown

• General: Pre-owned, shows cosmetic dirt buildup on heatsink fins, outer casing, and SO-239 connector hardware

• Front Panel: POWER switch, POWER LED, and TX LED indicators are intact with clean printed text

• Rear Panel & Connectors: ANT OUTPUT and TX INPUT SO-239 jacks are structurally intact but display surface dirt

• DC Power Lead: Attached fused power wiring harness is firmly connected to the chassis, but requires end-user terminal connector installation (bare wire ends)

Key Features

• 30W RF Output Power: Boosts 0.5W to 5W HT transmitter input up to 30 Watts output on the 2-Meter band

• Built-In RX Pre-Amp: Integrated helical resonator receive pre-amplifier helps bring in weak incoming signals

• Automatic RF Sensing: Internal T/R relay automatically triggers transmit amplification upon detecting input RF drive

• 12V DC Operation: Runs on standard 12V to 13.8V DC power (negative ground)

• Heavy Finned Heatsink: Solid aluminum fin chassis for effective passive heat dissipation
