I always had good results with Hustler/New-Tronics antennas both in the old CB Days (70's) and HF bands after that. The tuning is easy and nice bandwidth above 20 meters. I even used them on 75m. I however NEVER seen or heard of a "window mount" for those antennas. Please pictures or model number of this set-up.
Made in USA
From their beginning in Cleveland, Ohio, Hustler Antennas
have been produced in the U.S.A. for over 40 years. Since 1985 Hustler Antennas have been manufactured and marketed by New-Tronics Antenna Corporation
in Mineral Wells, Texas, on the western edge of the Dallas - Fort Worth metroplex.
Many here to help.
