Today I received an antenna that I ordered from eBay last week that cost a hefty $9.00 shipped. It is a Nagoya NA-701 with SMA male connector spec'd to receive 120/150/300/450/900 mHz. I installed it on my BCD436HP. The fit is perfect and it's about 2" longer than the supplied antenna. My un-scientific analysis suggests a noticeable improvement in receive signal quality compared to the antenna supplied with the scanner. Your results may vary...
