Today I could get it tuned. Like you said, phasing coils probably are different because I tried to tune for MURS by adjusting the length following the instructions of the G7-150-1 measurements. It didn’t work.


By using an antenna analizer and some patience, I could tune it to an SWR of 1.2 on 152.225.


Next thing I am going to do is measure the radials to see if they are the same as the G7-150-1. A friend of mine told me that they are 21 inches long. If mine are longer, I will fabricate them and check if SWR go lower. Here are the SWR measurements:


Frequency. ————- SWR 


150.725 ———————1.5

152.225 ———————1.2

154.550 ———————1.5
