Antenna for UHF VHF Links

163



10 El.Homebrew UHF Yagi for Satellites
Ideal relationship between length & Gain... for 3-4 DBd more Gain we need in practice about a double Boom in length and much higher number of Elements

144 mhz long yagi constrution details
Uses .125' 3.175 mm diameter aluminum elements, which are to be supported on two parallel non conducting lines that will not stretch

2 meter Halo antenna
Flat aluminium bar is the easiest material to make an antenna with as it is easy to bend and if 3 mm or more thick, is strong enough for most applications at VHF and UHF

2 Meter portable Zigzag antenna
All you need it some stranded hook-up wire, wooden or plastic battens as supports and a 102 inch 2.59m length of 450 ohm
