Potable Stressed Dish Antenna
This is a Potable Stressed Dish Antenna using umbrella. Though its reflector face is uneven, performance is better than homemade loop. This antenna has made easy phone QSOs!!
This antenna suit for AO-40 field operation. This was an umbrella, but it is unable to use under rain and wind. hihi.
D=110cm, f/D=0.4, 2.5 turn Herial feed
I'm remaking the reflector face to fulr compactly.
I made QSOs on AO-40 S1 mode using 12elements Twin Delta Loop. AO-40 S1 is easy SAT!!
