[TowerTalk] Frequency change

[WI8W]

Howdy,

I just assembled my Cushcraft A3 out back on a couple of sawhorses.  I set
the antenna for the CW portion of the band because RTTY is my primary mode.

How much can I expect this antenna to change in resonant frequency + or -
when I raise it to the top of my 50 foot AN Wireless tower located 4 feet
behind the house?

I am not sure what frequency of each band Cushcraft considers for the CW
setting.

thanks
