Converting a 470-694Mhz TV antenna for 433Mhz reception

It is not generally practical to convert an antenna for lower frequency operation. This is because, if you want to change the a given antenna design to a different frequency, what you do is scale it ...

How is the length of an inverted V affected by being too close to the ground?

Feed-point impedance of a capacitive antenna, like an Inverted V, is affected by four physical factors: Length of radiating elements. Adjusting the overall length so that the antenna is resonant on ...

How is the length of an inverted V affected by being too close to the ground?

Yes, somewhat. We could model the effect of height above ground on resonant length for an outdoor antenna. The effect I would expect to see is that lower height means more capacitance to ground, which ...
