In researching the antennae I found it is definately a Harada Power Antennae model RX-20. The replacement black mast is a PRXMB-5 the "B" is for the black mast, without the "B" you get the chrome mast. I was not able to find a direct drop in replacement. The good news is there are many antennaes that will fit close enough that there will always be something that will be useful to replace the Harada antennae. Many have the relay buit into them so you won't need the relay that lives behind the driver's seat if you change to another brand. There appears to be ample stock of parts right now, I found some at a local car radio shop. The mast cost me $30. In the future though it will get harder and more expensive to replace the mast so eventually we will have to find a replacement.
