need help designing 6 meter amp trigger

[CJD1]

I am trying to design a amp trigger at 6 meters. I intent is to create a trigger circuit via the coax at the load back to the amp. Maybe having a choke in series with a cap and resistor which is tied to ground, then using a switch short the choke to ground by passing the cap and resistor. Then on the output stage of the amp sense the change and forward bias a switching transistor. The coax to the load would only be several feet long and the amp produces around 100 watts. :roll:

Bias T

You can use what is commonly known as a Bias T. You put a capacitor in series with the center conductor and a choke in parallel with it. The DC on the choke only goes down the line that is not in series with the capacitor.

Your description is very much like this.

you need to add some 1n4148's as a clamp to develop some voltage to use to switch the switching transistors
