When a panel antenna is rated, is it rated for total gain when it is dual polarity? Specifically, if a panel is listed for 19 dBi dual polarity, do they really meany 2x 16 dBi?
I found some 15.5" 19 dBi single polarity antennas... if I use two of those (one horizontal and one vertical), is that the equivalent of a 19 dBi dual polarity antenna or 22 dBi dual polarity antenna? ------------------------------ On Tue, Jul 11, 2017 at 1:07 PM, Chuck McCown <[email protected]> wrote: > He is limited in area he can use: 16” x 64” > > *From:* Jaime Solorza > *Sent:* Tuesday, July 11, 2017 11:04 AM > *To:* Animal Farm > *Subject:* Re: [AFMUG] Connecting Antennas For Higher Gain? > > Well there are 8 ft grid dishes with 26 to 28dB of gain....what about one > of those new horns?
