Antenna for digital TV

35 posts in this topic

Antenna for digital TV is no different from antennas for analog TV. choose from a large Ku. 
Specify which channels are broadcasting UHF. the antenna should cover the range(500-800MHz).

 

This is a realization of VodkaMan friend.
Some improvements for this type af patch antenna UHF:
 Mounting studs M6 with nuts and washers. Line powering with ramps instead of fillets (I think smarter).
 Reflector rectangular 340mmx290mm, the distance between studs 120mm. 
Patch - 208mmx208mm truncated cylinder 214mm installed at a height of 65 mm (the gap).
Director - 173.6 mm in diameter, at a height of 95.5 mm from the reflector (the gap).
Material - galvanized 0.5 mm.

I think there is no other option to reduce the size of antennas - MIMO 850Mhz Band5 =UL 824-849/ DL 869-894 MHz

with one patch antenna gain is 9DBi, and if the second patch to put on top of the first patch, the antenna gain will be great?
