HB9CV Antenna
Frequency [MHz]
λ [mm]
Length L1 (Dir.) [mm]
Length L2 (Refl.) [mm]
Length L3 [mm]
Length L4 [mm]
Length L5 [mm]
Boom Diam. [mm]
Radiator Diam. [mm]
Spacing [mm]





✈ Notes :




• Spacing is the Distance from the Boom to the 'Gamma-Match'.
• Feeding the Antenna can be done at the Director or at the Reflector.

(If you are a HAM): Design and Adjustement is easy, as with the Capacitor you can tune the Resonance by some MHz with no effort.

(If you are my boss): Design and Adjustement is very tricky and can only be done by smart engineers with sophisticated Measurement Equipment.


HB9CV Antenna


A HB9CV designed for 1276 MHz, C = 1.8 pF (Hi-Q), optimised empirically.
