Default MA5B Newby's misunderstand of Beams?

Please e-mail me directly if you think you know what my problem is and
how to resolve it. I have just installed an MA5B Cushcraft Mini-Beam
and all seems fine. SWR's are normal, Coils are installed
correctly...all is well except a major noise increase that rides along
with the signal received. Like hearing a weak station and switching on
a receive amplifier (Bringing noise with the signal) I believe in my
heart I have constructed the Beam IAW the Cushcraft manual. Coax is
new and connection are correct. Could this noise be because of the
matching network being bad. I switch over to my Dipole on the ground
and the signal changes from static voice to clear audio right down to
absoloutly no noise when transmitter un-keys. Very frustrating. Help
and hilfe bitte!
