MFJ-2286 7-55MHz Portable Vertical Antenna HF Base Antenna is over 18 feet long fully extended, but disassembles and collapses to 28 in seconds! Tapped loading coil covers 7.0-55.0 MHz without gaps. (6 to 40 Meters)! Great for Transmitting Ham Bands, and outstanding for image-free Shortwave broadcast Too!
