Logarithmisch-Periodische 2mt und 70cm band
Yagi antenna usually only usable on a narrow frequency band -Monoband. The situation is different with so-called logarithmic periodic directional radiators

Portable 6meter yagi
Boom length of not more that 2M, Reasonable gain,Low cost, Ability to dismantle easily, for transportation

Portable Yagi work on 144MHz
The antenna is matched to the coax using delta arms and a 4:1 coax balun to the dipole. The balun was constructed in the standard way using a loop of about 71cm

QHA Quadrifilar Helix Antenna
Misure per una copertura da 132 a 138 Mhz quindi per i satelliti polari
