Which way should the resonant frequency go as the height above ground is 
increased for a 40 meter rotatable linear loaded diopole. If the swr is 2.0 to 
1 at 7200 with the length set for 7200 10 feet above ground will the resonant 
frequency go up or down as the antenna height is increased to 78 feet or will 
it stay at 7200 with just a lower swr.  thanks for any help. Van W4GIW
