I have had no issues at all using 25cm size dual polarity 5GHz dishes (nanobridge and nanobeam m5) through single pane older glass. Adds maybe a few dB attenuation. Still achieved solid mcs13-mcs15 links for PTP with the right channel selection, even in a very rf noisy urban environment. On Feb 20, 2016 3:00 PM, "Christopher Gray" <[email protected]> wrote:
