   Can you give dimensions please.
   Does it feed directly into 50 ohm cable?

     Hi Tim,
     Yes, it does. However, it’s trimmed for low SWR which (without any matching) is probably a little way off resonant. However, in practice it worked well for what it is. I don’t recall the dimensions but the driven element is a simple half wave dipole on the required frequency, reflector and director size and spacing using the standard rules.
