[TowerTalk] What are est of frequency chg for ten meters?

[VE6JY Don Moman]

It will depend on the yagi, but from experience the OWA design, with the
close spaced first director, can be tuned near the ground - pointing up in
the air as much as possible is always advised - with almost no change in SWR
and bandwidth.
