UB5UG snake antenna









N.B.
1. Antena has horizontal polarization!
2. Antena is scalable for other bands too.
3. You can add more bars to get additional gain - 1.1 dB per pair:
5 bars (standart) 6.2 dBd
7 bars 7.42 dBd
9 bars 8.45 dbd

SWR remains within acceptable range (<1.6 within 70cm band).
