Repeat the process one more time and then recheck after raising the antenna to its final height You can see from my SWR chart that i missed by a hint because of impatience. The antenna is usable over the entire band as tuned, and the high frequency side of the SWR chart does offer the highest forward gain. . .(excuses, excuses). To install the antenna, i used a 40' four-section push-up pole, a wall-mounting bracket, and a...
