The GRA-TLV2015 is a compact, high-performance Portable HF Delta Loop Antenna designed for operators who value simplicity, efficiency, and portability.
Unlike traditional delta loop designs, it achieves direct resonance without an ATU (Antenna Tuning Unit) — delivering outstanding SWR and transmission stability right out of the box.
Unlike traditional delta loop designs, it achieves direct resonance without an ATU (Antenna Tuning Unit) — delivering outstanding SWR and transmission stability right out of the box.
Its closed-delta loop structure ensures balanced current flow and uniform radiation, while the modular coil system allows seamless switching between 14 MHz (20 m), 18 MHz (17 m), and 21 MHz (15 m) bands.
Built for rugged use, the antenna features carbon fiber telescopic arms, stainless steel quick-lock fittings, and a precision aluminum center hub housing a 1:1 UHF balun for a perfect 50-ohm match.

Applications
The GRA-TLV2015 is purpose-built for field deployment without the complexity of antenna tuners.
It can be set up vertically for full radiation efficiency, or angled at 45° in limited spaces.
A ±15° adjustment mechanism helps operators easily avoid physical obstructions.
Ideal for POTA, SOTA, and EMCOMM where reliability, fast setup, and consistent performance are crucial.
