Thanks, where we were it's hard to get copper pipe... but the irrigation tubing you can get almost anywhere. Those oval antennas can be great, though. I didn't know they had a low angle but I do know they have a wider range of acceptable frequencies....
Thanks to the work of great organizations like Prometheus Radio [http://www.prometheusradio.org/] there are about 1500 Low Power FM stations in the FCC's bailiwick [http://www.pewresearch.org/fact-tank/2016/09/19/nu...]And they were ready to license 13,000 more in 2013, including in a lot of urban areas. I'm out of the US now so I'm not sure if they're taking license applications still, but if not just lobby and help Prometheus start another auction.Outside the US, many countries have progressive FM policies, for instance hundreds of new stations in France and the UK in the last few years. As big FM dies, we should create 100 stations in the space where there used to be one big classic rock cyclops.
