Two CHA CFM-34 masts spread from a CHA HUB in a V to support the upper corners of the inverted delta. The completed antenna occupies approximately a 50 ft diameter area.\u003c\/p\u003e\n\u003cp\u003eThe LW-TDL is offered around two controlled electrical paths. The HYBRID version uses 3\/8 in ring-terminal leads for a CHA HYBRID-MICRO or CHA HYBRID-MINI. The BALUN version uses #10 spade-terminal leads for a CHA 4:1 BALUN followed by the CHA URT1 remote tuner. The two versions are not interchangeable at the feed point.\u003c\/p\u003e\n\n\u003ch2\u003eChoose the version that fits the station\u003c\/h2\u003e\n\u003ch3\u003eCHA LW-TDL-HYBRID — 80 through 10 meters\u003c\/h3\u003e\n\u003cp\u003eThe HYBRID version covers the documented 3.0–30.0 MHz product scope.
