Ten-Tec Model AC-4 SWR Meter Matched PM-1 Series New in Original Box

This item is part of a friend's Ten-Tec Collection and is a rare find new in the box. It will work with all QRP gear and matches the PM series transceivers.

Ten-Tec Model AC-4 is a vintage low-power SWR meter (also called an SWR bridge) from the late 1960s to early 1970s. It was designed primarily for QRP (low-power) operation, especially to pair with Ten-Tec's Power-Mite series transceivers (like the PM-1/PM-2) and modular kits (MR-1, etc.).Key Details and Specifications

Purpose: Measures Standing Wave Ratio (SWR) for antenna tuning and matching on HF bands.
Power Handling: Usable from ½ watt to 250 watts (though optimized for low power/QRP; best accuracy at 5-50W or less).
Design: Simple bridge-type meter, typically with SO-239 connectors, a meter for forward/reflected power or SWR ratio, and controls for calibration.
Era: Produced around 1969–1972, part of Ten-Tec's early QRP accessory line (alongside the AC-5 low-power antenna tuner).
Build: Often sold as a kit or assembled; compact and rugged for homebrew/QRP use.
