Topband: PreAmp Recommendations

[Ian Keyser]

If your preamp has poor IMD performance it is imperative that a good high 
pass filter is included to ensure MW BC stations cannot get to it.

Better still a passband filter for the desired band, however either will 
still be affected by the strong local in band signals.

Over here I would look for the best IMD figs..... Due to manufactures 
optimistic advertising I would want a 3rd order intercept point of at least 
+20 dBm when on a -30dBi receiving loop just to cope with the local MV BC 
stations. I assume that you have similar problems over there.
