MAIN SPECIFICATIONS The main advantages of the RH-DX620S antenna are that it is small, lightweight, made of fiberglass and requires a single support to be installed.

This results in much reduced coupling to nearby conductors, so that losses and interference problems are reduced. - Page 3 IDENTIFICATION OF THE PARTS OF YOUR ANTENNA !1 Acrylic mounting plate !18 units - M6 x 45mm (0.24 x 1.77") Cap head screws !2 units - M5 x 20mm (0,19 x 0.79") Hexagon Bolts !18 units - M6 Hexagon nuts !2 units - M5 Hexagon nuts !18 units - M6 Lock washers !4 units - M5 Flat washers...
