Scanner receiving

[Bonkk083]

Will a scanner receive a better signal without a splitter, multicoupler or amp?

Spliter does what it says, it splits. So on weak distant signals, you will have issues.

Multicoupler, if it has zero loss between ports then it’s not degrading your signal so there should not be any difference.

Amp. How is it being used? If you’re using the amp to basically receive the signal because it’s weak then you might not hear it at all without the amp. If the amp is overloading the scanner then it would be better to attenuate the signal before it hits the scanner

How can I find out loss between ports, maybe this is i

Frequency Range: 25 MHz to 1 GHz 4-Ports
Nominal Impedance: 50 ohm
Port-To-Port isolation (min): 22 dB
Return Loss (all ports): > 20 dB
P1dB = 17 dBm (output) 3OIP = 32 dBm (output
Coupler Gain/Loss: +2 dB to -1 dB (max) over frequency range
RF Connectors: BNC (standard)
Mechanical: 4.375 X 2.375 X 1.250 inches (L.W.H)
Case: Die cast Aluminum, Black powder coating (standard)
DC Power Connector: 2.1/5.5mm coaxial (standard)
DC ower Requirements: +12VDC (nominal) @ 85 mA

Using my Stridsberg MCA-204Mil I can't detect any loss between ports, while using 3 of the 4 ports, with term resistor on the 4th.
