Default What About Scanner Reciever Antennas for Shortwave Radio Listening (SWL)

Thanks RHF! Excuse the top posting, but your information is utterly
magnificent...kudos.

My thought on the MFJ 1020C active pre-amp is that such is self contained,
easy to pack, has the appropriate controls, comes with a vertical
telescoping mast 50+ inches and looks like it would be easy to setup and
use.

Wires are nice, but messy on luggage and sometimes airport security get
curious.

So the question is does the MFJ 1020C do the job.

FIRST - IMHO - You Do Not Need a MFJ-1020 Active Antenna
for the Icom IC-R20 Wideband Scanner Receiver.

WHAT YOU DO NEED IS : A Better-Bigger-Longer Antenna
Passive Antennas that will Capture and Deliver more Signal
without Overloading your Scanning Receiver.
