Simple Dipole Antenna

67 posts in this topic

Here are some quick notes about the parabolic type dish antennas you might find.  The actual antenna is a normal half wave dipole with an integrated balun and is located inside the sealed plastic cover.  The mesh screen is the reflector which concentrates the RF energy onto the antenna.  That is how dish antennas increase the received or transmitted power level.  Also, wireless cable service providers frown upon giving away their used dishes as they think you're going to steal cable service.

This design looks like easy to made and it's great to use with dish. Hmm, have spare sattleite antenna dish but for 1280 Mhz. When will have more time will ask for dimensions for that frequency :)

,,,good, this is a general scheme...!!!

,,,baluns device (a device that provides coupling the symmetrical antenna and asymmetric feeder) made in a quarter-wavelength glass the base of which is connected with the outer conductor of the hard coaxial cable...

My friend, please explain how to properly power this design. I don't understand at all. :)

The question is. The sleeve balun is connected to the dipole ?
