Here's a report on bandpass filters I prepared a year or two ago that 
ran in National Contest Journal.

Also look at

for practical info on stubs, how they work, and how much to expect from 
them.

I strongly agree that the 5B4AGN group purchase kits are a huge bargain, 
and their performance blows away all but the W3NQN filters that Array 
Solutions sells for a LOT more money. And Bob Henderson, a Brit living 
in Cyprus, is a first rate engineer and a first rate guy.

The ICE filters are junk, and ICE is out of business.  The Dunestars are 
a bit better, but still fail more than they should. Bob measured several 
of the 4O3A filters, and they are in the report.
