[TowerTalk] RF Inquiry HI-Q Filter CF5KV

[Rob Atkinson, K5UJ]

One more point I'd like to make I just thought of this morning is that if 
you decide to make your own line isolator with beads, it is very important 
that you buy from a vendor who can specify the mix.  I made the mistake of 
buying them from RF Parts.  They are a great vendor of a lot of good 
products but in the case of ferrite chokes, they do not specify the mix.  
This was my mistake -- buyer beware.  I wound up with chokes that measured 
low Xl at HF and almost nothing on 160.  I don't know what the mix was but 
it apparently wasn't 43 or 77.  but at the time they were about 50% the cost 
of other vendors.  This was another case of you get what you pay for.
