Many
scanning monitor receivers suffer from
interference on the VHF Air Band
118-138MHz, especially when connected to external
base antennas such as Discone’s, etc.
The use of wide band RF antenna RX pre-amplifiers, particularly
those without special band pass filtering may often make matters
even worse! Interference is quite common from the following
sources: FM Broadcast Band 88-108MHz,
| Paging
Frequencies around153MHz,
|
RX
ONLY
|
Shortwave,
PMR, etc.
The SSE Band Pass Filter
ABF0604 will greatly
reduce the problems and in some cases totally
eliminate them. A great deal of attention has been given into
achieving a minimum of insertion loss in the 118-138MHz
band.Order
