FS: Good condition, used GAP Challenger is designed to be mounted directly on the ground or elevated on the roof. Roof mount does not gain any specific advantage due to the 'elevated ground' structure. The CHALLENGER covers the bands 2/6/10/12/15/20/40 and over 130KHz of bandwidth is provided on 80m. (I have not tried this antenna on 2 meters). The antenna requires a counterpoise of three 7.5m wires (included). They may be buried or just scattered on the ground. Symmetrical deployment is not critical. Adding additional wire will not significantly improve performance. The operating center frequency on 80m is set by means of an integrated fixed capacity. I do not remember what exact frequency the 80 meter cap is set for. You will have to make a trip to your local hardware store for 3-4 U bolt type clamps to secure the insulated bottom of the antenna to your mounting pole. This has been in the rafters of my garage for several years.
$120 cash at time of pick up in Douglas County, Missouri, about 90 miles East of Springfield, Missouri. NO SHIPPING as this is way too long. My location is correct on QRZ dot com.
