I have a simple scanner/shortwave receiver and have recently installed a
wire antenna. I have been able to pick up stations over 500 miles away.
However, it seems as though the stations are grouped in very narrow bands.
Is there a way to make the antenna "look" longer or shorter electronically
so that I have a greater range of frequencies? Thanks your help in advance.

Hi Matthew,

There is a certain amount of vagueness in your description. Is a 500
mile range unexpectedly good, or bad? Over what band of frequencies?
How long is the wire? How high is it? Put a tuner between the two
and you kill the scanning ability to some degree, however a tuner may
be necessary for good Shortwave.

For instance, in the Shortwave region, that is not particularly good,
but for VHF that would be gang-busters.

As for the grouping of active signals. What frequencies? It would be
a common observation anywhere across a lot of frequencies, but if you
were worried about Shortwave being deaf from 9.5 to 10 MHz, you would
have a complaint; bump it down between 9 and 9.5 and that would be no
surprise.
