Description

Counterpoise kit Model 1251 helps solve RFI/TVI and "Hot Chassis" problems caused by a lack of proper RF ground. Useful for condo and travel situations where PVC plumbing makes classic waterpipe grounding schemes impossible or where a ground is too far away. While NOT a substitute for a vertical's radial system or for a safety ground it does provide a tuned counterpoise to satisfy the transmitter's need for an RF ground path.

Key Features & Specs
  • Function: Tunes a counterpoise wire (10–50+ ft recommended, insulated) to provide a low-impedance RF return path, reducing RF in the shack and improving antenna efficiency.
  • Coverage: HF bands (typically 1.8–30 MHz; tunable via variable inductor and switched capacitors).
  • Metering: Built-in current meter for easy tuning (maximize current for best match).
  • Design: Simple circuit with high-quality components, compact metal enclosure (approx. 6" x 3" x 4"), SO-239 input from rig/tuner, output for counterpoise wire; no external power needed.
  • Build: Straightforward assembly with clear instructions—great for beginners; many builders report quick builds and immediate results.
Praised in eHam.net reviews (average 5/5 from users) for effectively eliminating RF bite, improving tuning on random wires, and outperforming some commercial alternatives (like MFJ-931) in real-world use—ideal for QRP, travel, or limited-ground setups!
Ten-Tec T-Kits are high-quality amateur radio kits produced by Ten-Tec, an iconic American company founded in 1968 (originally as Tennessee Technology) in Sevierville, Tennessee. Known for manufacturing reliable HF transceivers, receivers, and accessories, Ten-Tec became legendary in the ham radio community for its innovative designs and excellent performance.The T-Kit line (introduced in the 1990s and continued into the 2000s) offered affordable, beginner-friendly projects for hams and experimenters. These kits focused on QRP (low-power) equipment, including single-band CW transceivers (like the popular 1300 series for 20m, 30m, 40m, etc., with models such as 1315, 1320, 1330, 1340), regenerative shortwave receivers (e.g., 1253, 1254), direct-conversion receivers, antenna tuners, transverters, wattmeters, and modular boards for custom builds.They were praised for being easy to assemble, well-engineered with high-quality components, and delivering solid performance once built—often outperforming commercial gear in their price range. Many hams built their first radios with T-Kits, and they remain sought-after by collectors and builders today.Your unbuilt T-Kits are rare collectibles, offering a fun project or a piece of ham radio history!
