This antenna is EXTREMELY easy to assemble, requires no tuning or adjustments and VSWR is under 1.6:1 continuously from 3.5MHz – 57MHz! It is not a 1/4 wave vertical, but an end-fed long wire type antenna with a matching transformer in a vertical position. Broadband: TX 3.5 – 57MHz RX 2.0 – 90MHz VSWR: 1.6:1 or less Max Power: 250W SSB Impedance: 50 Ohm Length: 23’5? Weight: 7 lbs 1 oz Connector: SO-239 Mast Size Required: 1?-2? diameter Max Wind Speed: 67MPH If you have the space, budget and desire to erect a full size antenna system we suggest you do so… bigger is better…however…if you live in an antenna restricted area and must manage with antenna or space restrictions or you simply wish to operate incognito you will be forced to make significant antenna compromises. The CHA-250B will make the most of these circumstances! Additional Model #'s 215-CHA-250B 215-CHA250B CHA-250B CHA250B
