 As we have found out while experimenting, in HF almost everything becomes a lowpass, but not in the way we wanted it to be. Things on how to make the PCBs should be added here.
+If the wavelength is less than approx. 10 to 100x the size of your components or wires in the circuitry, you will have lots of parasitic effects due to line inductance or stray capacitance which alter network behaviour. Example: At frequencies about 1 GHz, (wavelength 30 cm) you cannot use wires etc. longer than some millimeters without considering its parasitic effects.
