This is my own model 2x1/2 colinear for 435 MHz.
SWR on central freq is 1.1
Wide band - 420-450
Without montage bracket for shipping weigth and low price. Bolts, nuts- stainless fasteners.
I make this antennas for our army like volunteer. And some fotos from real War positions. Doing well.
My callsign is UR8LV (EM1LV)
