This is directed specifically at anyone who has experience with the Yaesu ATAS-25 antenna system. I'm planning to use mine for portable operation, such as SOTA activations.
I guess I'll just dive right in:
On the first page of the instructions is a chart showing the number of radiating elements to use for each particular band. For 28 MHz, one of the options is "No Connection"; for 50 MHz, "Do Not Connect"; and for 144 and 430 MHz, "Not Used." Can someone explain the difference between these to me? The "Not Used" for 144/430 seem pretty self-explanatory, but "No Connection" and "Do Not Connect" confuse me. It seems that if I took these instructions literally, I'd be setting it up the same as if I was operating on 144 or 430; I'm sure this isn't what they mean, though. I'm hoping someone out there experienced with the ATAS-25 can clarify for me what they're telling me to do.
Thanks in advance!
