I was reading about a usb dongle and program called shipxplorer and in their hardware section, they have a outdoor antenna that is 162mhz. Since railroad is 160-162mhz band, I wondered if it would be close enough to do any good. Right now on Amazon, the antenna has a 1 star review but nothing was posted on why it was given a 1 star review. Here’s a link to shipxplorer website and the antenna is about half way down the page. I may order 1 just to do a review and compare it to my diamond D130-J.
