CAPACITY HAT DESIGN: Expands the top loading area of electrically short HF antennas to help improve current distribution and support more efficient low band operation.
TORAY CARBON FIBER: Built from layered Japanese Toray carbon fiber cloth with high pressure forming for excellent strength, rigidity, durability, and low weight.
BUILT FOR LOW BANDS: Especially useful when operating compact antenna systems on 80m, 60m, and 40m where available radiator length is limited.
LIGHTWEIGHT FIELD SETUP: Weighs about 5.3 oz, supports up to 400W, and opens to 37.8 x 37.8 x 41.7 in, providing a large top loading structure that packs down to 21.9 in.
COMPATIBILITY & USE: Direct fit for GRA-7350T(C), GRA-RPG, and GRA-AT330T(C) via M10 x 1.0P. Install on the radiator side only. Not a standalone antenna or RF ground radial.
