This question takes this discussion even more off topic.

I just acquired a 2.4GHz phone system.  I works really well, except when I
need to go
trough a concrete wall!  I was wondering if anyone can suggest specs for an
antenna
that I can mount on the other side of the wall to get back the range that I
have become accustom to?

Also, is it possible to attach this external antenna onto the existing one
in the base
or will I have to crack open the case to attach it to the PCB directly?

I know nothing about RF and need as much info as I can get.

Thanks.
