Home made VHF rf choke. It has a typical value of 0.3uH made by winding 15 turns of 0.2mm enamel wire over a high value resistor (27K 1/2watt) as a former. Inductor leads are soldered across the resistor leads and the instant glue secure the winding on the former.
Most of my home made vhf rf amplifiers uses this rf choke in its bias and also in the DC supply section. Commercial vhf choke generally comes in a small package suitably for smd but since I have so many enamel wires in my junk box, home brew comes in handy. ---73 de du1vss
