- Lowe's HIW carries empty metal cans with metal lids in gallon and quart size. However, if you are going to leave them outside they will need a good coat of paint as they will rust very quickly. Clint

- Tom, For several reasons, RG6 is a lousy choice for stubs in 50 ohm systems. The fundamental problem is that stubs work by shorting out the undesired signal.That requires very low resistance of both

- OK, BUT: because the effectiveness of stubs is directly related to R (at the freq of interest), foam coax is not the best choice for stubs unless the conductors are also larger, because Vf requires t
