Great reception close to patio umbrella

Hi guys,

I'm finding a gear excellent reception when lining up my HP2 close to my patio antenna. Can someone give me the science behind this?

could be

direction of the signal so
on one side metal reflects radio waves back to the radio.
and you are called stray capacitance to ground.

Dumb luck.

If the umbrella pole is metal, it will reflect signals. If the antenna is located in a spot where the reflected signal is in phase with the original, you'll get a signal boost. If the reflected signal is out of phase with the original, it will decrease the signal. If the pole is between the transmitter and receiver, it will block the signal.

The effect you get will be random, depending on the wavelength of the signal you're monitoring, the exact distanct between the antenna and the pole, and the location of the transmitter antenna, receiver antenna, and pole.
