Forum: Virtual Classroom - Yagi Antenna Help Required.
Yagi Antenna Help Required.Hi All, I am based out of India and new to Antenna design. I got my SDR a few weeks ago and referring to PDF "THS-NA-TSI-PR-02-1.0_70cm_High_Gain_Antenna_Construction" for making Yagi Antenna. However, I have few queries of mine if someone can help with.
1) Will a normal non-insulated copper wire (used for earthing in electrical wiring) suffice my requirement to make its reflector and drivers? Dia 4 - 4.11mm X 3 meters. Many electrical dealers are confused on what type of copper wire is required even after giving the specs. If I get a thicker dia wire will it work?
2) Normal Coax cable used for TV-Satellite cable channels will do? Most of the sellers are not aware of what specifications it has, like RG59 or RG6 Diameter, since they sell it in bulk?
3) Some experts have suggested that impedance matching is important and most antennas are 50 ohm so need RG8 or RG58 cable (and not RG6 and RG59 - 75ohm as mentioned in the document).
Please help. 29th Nov 201708:36
