How about this:

(take care with line wrapping of the URL, above)


10 for $10.00 plus $2.50 USD -- comes to $1.25 a piece, and provides
for a fatal error in construction/use.


They are a bit small, sharpen your soldering iron, but should be
easily "do-able."

The IMD is way worse than the Minicircuits device Telemon referenced.


- I referenced the Minicircuits MMIC.
- I think the specs look pretty good for a MW/HF loop pre-amp.

- - I wonder if Wellbrook uses a MMIC?

- Why bother with Wellbrook ?
