---I found a helical type vertical antenna here that might be worth
trying.

There are other useful antenna links on the site.
There also some commercial active antennas that use a vertical whip
element such as this one:MFJ-1020C

Since vertical antennas favor lower angle signals,i wonder if a
vertical antenna might be useful for logging stations on am

frequencies

that otherwise might not be heard ?I have seen helical vertical
antennas for ham radio including 40 meters.I am wondering if there is

a

design in existance for MW frequencies.Metal whip antennas that come

on

some older cars are the only vertical type i have seen so far.Perhaps
this is an area we can do some experimenting in.Of course one

drawback

might be that verticals are more prone to electrical noise
pickup.Perhaps they would be helpful in quiter reception areas.
