Quick Q about radio signals in current climate

[Highlander]

The strength of the output will always help you, the more power the stronger the signal,.. but the propagation is always there,

Propergation is also to do with radio waves penertrating building and mountains, not just the weather,.. the higher the frequency the shorter the wave lengths so building can be a problem... HF is not the way to go for most people

Vhf, has wider wavelengths and so can deal with obsticals better,... but the weather will always be an added problem
