2m 70cm hanger dipole (www.ea8dhy.es)

Hi! I wanted to share a simple dual band dipole that I've built recently. It has been performing perfectly fine for me the las weeks given the fact that I'm at the first floor of a tall building surrounded by tall buildings also.

Also it's extremely cheap to build. To get it out I'm using a fishing pole.

Maybe someone in the same situation than me could find it useful.

Is this for FM? Most people are using vertically polarized antennas for that. You could turn it on it's side, and feed that coax sideways for at least a few feet.

Yes, I'm using it vertically polarized. The fishing pole allows me to put the antenna away from the building through the window to have a better reception. The result is like a T rotated 90 degrees. If I want to change the polarization I only have to rotate the fishing pole. But I'm only using FM and everybody else is using vertically polarization.
