This antenna was designed for "T"ransmitter hiding. Fitting the requirements of directionality, high gain, and portability. This antenna was derived from the ARRL Handbook information on Quagi's and Yagi's; in the absence of two meter Quagi informa- tion, UHF Quagi dimensions were scaled into 146 MHz use.

This antenna has high gain (partially due to the wide direc- tor element spacing). The antenna is tuned for 146.565 Mhz. giving an approximate 14 db gain. The boom of the antenna is made from two 8' 2X2"'s and an additional 3' 2X2" for the Quad part (reflector & driver) of the Quagi. The construction methods of the WA6TEY Quad was used for the reflector and driver portion of this Quagi.

                Total boom length 17.8 ft.

The feedpoint of the Quad makes the determination as to the polarization characteristics of the Quagi antenna. Insure the feed point is perpendicular to the Yagi type element directors. Quad feed points are attached opposite conventional thinking! Rotate the WHOLE antenna for either horizontal of vertical polarization.
