It was designed with
Bit in Mind.
I saw someone post the
QRP Labs one???? So I thought I would show a better one.? ha..
This looked real good
on the SA for return loss.
Its perfect for bit,?
you never tune long enough to hurt it?? And you can stick it
right out the back with the BNC Adaptor.
The biggest cost is
the BNC connectors.
Stick in your coffee
cup too, to reheat the Java!
I still have the
Heathkit Can -Tenna somewhere?? I remember the can rotted out,
I had to go to the paint store
and buy a new gallon
paint can.? I used to tune the SB220 into it.? I think I put
Automatic Transmission Fluid in it.

Or, how about
150W DL with builtin wattmeter for under $20? This was a build
our group did a couple of months ago. The lid is shown here.
The resistor network sits in a mineral oil bath. The downside
is that this is considerably larger than yours and a little
more expensive.

Hey,
speaking of Dummies.? Here is one I came up with.
Its 4 -? 3W resistors.? Has RF tap (0602 Component)
either for a resistor or Cap.
Shky diode and cap.? Place for LED (0805).? 3 Pin
Molex for output monitoring.
You will have to fiddle with the values.?? Layout
has lots of ground plane, both side of the PCB.
And you need the Male BNC Adaptor to go to the back
of the Bit.
I got lots of PCB, $4 or Kit $12 (Includes BNC
Adaptor, shipping, Paypal) US.
PCB can be shipped in and envelope, but the Kit gets
a small box.
email me for more info
