[TowerTalk] FW: parallel tuning network

[Pat Barthelow <aa6eg@hotmail.com>]

Hello Len,

RF components of high power capacity are really neat to work into real tuners, 
and other RF projects

Looks like you could possibly make an L network with your two components...


Here is a list of sites with images of RF power inductors, and
capacitors.  Take a look and send back the closest images to what you
have so we can get an idea of your component's values, and power
ratings in the 160 meter application.


All the best,   Pat Barthelow   AA6EG    Skype:  sparky599
