Quick, simple question:

Would a normal aluminum can be any good for RF shielding of a balun, or
would it for some reason not work? Should I connect it to ground?

What does a transmatch do for me that a normal balun/transformer won't do
for me?

Thank you for your time.
Sincerecly,

Well IF cans are made of aluminum so I would think a can would work
fine. Normally one should keep the walls of the can some minimal
distance from the coil windings. IIRC the radius of the can should be
something like 2-3 times the dia. of the coil.


I believe that I've read that the distance from metallic objects
should, at a bare minimum, be at least 1/2 the coil diameter. So that
means 2 times minimum, giving 1/2 of coil diameter around the sides.
3 would be much better. Aluminum is good shielding material; onlt
thing better would be copper (or silver).
