Here are the resonant frequencies I measured of a 10m half-wave dipole
on a telescopic push-up mast at various heights above ground in my back
yard:
5ft 29.359MHz
10ft 30.499MHz
15ft 30.889MHz
20ft 30.407MHz
25ft 30.179MHz

## scale that up to 40m... then it becomes a 205 khz increase when going from
20 ft..to 100 ft. But I dont know if scaling or extrapolating the 10M data
is valid.
