Car Shortwave Radio (2)

I was routinely listening to Radio Australia and other stations using BST-1 Car Shortwave Radio with my PBA-MLA4 Mini-Whip antenna in the morning time during my commute.  In my commute route there are a few particular points where I am suffering from MW station interference.

I have just obtained another whip antenna that was developed by the same manufacturer of BST-1.  It is a 2-feet mobile whip antenna that looks quite normal.

Then I tried it today.  The performance was actually much better than the Mini-Whip.   There was no interference from MW stations.    It was also interesting that when I tried these two antennas for Perseus SDR, the Mini-Whip peformed significantly better than this 2-feet whip.  It seems that the design of BST-1 is optimized for this whip antenna.
