Reasonable height for a good DX dipole is recommended by Mr. Braun, Siemens
engineer as 0.4 of the wavelength. For our majority readers using outdated
English units of measurement, this comes close to 216 feet on 1.85 MHz,
112 ft on 3.55 MHz and 56 ft on 7.05 MHz.
Famous "Fungo" tower of IR4T is just about right height for 160m dipoles and
you do NOT have to drive them that RF hard as there are NO ground losses :-)
