Building a 23cm dipole array for SWR 1,1:1 over entire band
After an article in RadCom july 1997 ham magazin i found a nice piece of antenna to build.
It had 10dbi gain and worked over 1240Mhz-1300Mhz with 1,1:1 in SWR.
Could this be true? i had to build one, in mind i had the use for it as an ATV repeater antenna.
The material is 400mm+400mm aluminiumplate about 2mm thick, 6 pieces of brass 6mm pipes a: mm more later on ... here is the pics...
6pieces of nylon/teflon (not critical) on picture is teflon rods 15mm dimension 60mm long. Elements mounted 50mm from groundplane.
NOT FINISHED YET:-)
Here is what it looks like to this date:
