DIY Hi-Gain Antenna on Cheap ;)

August 31st, 2007


Very Cheap Dipole feeders – they are easy to be build and you do not need a lot or expensive materials. Everything here can be made from wire or scrap /I watch too much scarpwars on Discovery channel πŸ™‚ /

I found some very interesting looking feeders for dishes – VERY cheap to make, first is made only from feeder line πŸ™‚ or simple coax.

A simple dipole feed. Good solution to illuminate parabolic constructions (solid, grid etc.) Heliax holds the dipole, as well as feeds the N-type female connector to the back. Tests shown 4 dBi (against Lucent 24 dBi parabolic grid). “
