I am co-locating the guys for the 40-ft / 12m mast with the 4-Square on 40m. Some careful measuring and lots of muscle was required. QUAD: This is a multiband antenna that ideally needs independant feeders for each band and a rotator. I have a mast-head remote switcher for this. Similarly, I need control lines for the 4-Square. More details about the 4-Square antenna in a later video. Have fun. Enjoy your radio. Callum.
