Re: [Amps] rf choke on output

[Peter Chadwick <g3rzp@g3rzp.wanadoo.co.uk>]

One function is to stop the pi tank components floating up towards the HV 
supply if there is no dc connection to ground. If you put two capacitors in 
series, then applying DC will lead to the junction floating to a voltage 
determined by the capacitance ratio. This can give problems if the antenna has 
no DC connection e.g. a dipole: you could get flashover in the loading 
capacitor.
