The GRA-TLV2015 is an advanced Portable HF Delta Loop Antenna designed for operators who want maximum performance without the complexity of additional tuning equipment.
Unlike typical delta loop antennas that depend on an external ATU to reach proper resonance, the GRA-TLV2015 features a frequency-specific modular coil system and an optimized closed-loop structure that enables direct resonance with no external tuner required.

This tuner-free operation is achievable when the antenna is installed with the correct coil module, proper feed-point alignment, and recommended vertical or angled setup as described in the user manual.
With these conditions met, users can expect stable SWR, clean RF performance, and consistent signal strength across the 14 MHz (20 m), 18 MHz (17 m), and 21 MHz (15 m) bands.

The antenna’s lightweight carbon fiber telescopic arms, precision-machined aluminum center hub, and stainless-steel quick-lock fittings make it highly durable and easy to deploy.
A built-in 1:1 UHF balun provides an accurate 50-ohm match, ensuring efficient RF transfer and low noise operation even in portable environments.
