My expeirence is that the grids are on par, gain-wise, with the solid dishes. The solid dishes have MANY RF advantages, but a 26 db grid will do 26 db and 29 dish will do 29.
the solid dishes have advantages in stability, beam accuracy, front/back ratio, and so on. But the gain is the gain, it seems. ----- Original Message ----- From: "Steve" <[EMAIL PROTECTED]> To: "WISPA General List" <[email protected]> Sent: Sunday, April 22, 2007 8:27 AM Subject: Re: [WISPA] 5GHz Amps > Does anyone have some real-world experience comparing the grid with the > solid 5.8 antennas. > Is the listed gain accurate in describing performance? or are there > additional advantages of the solid dish at equivalent gain ratings? > I have only installed grid at this point, due to local high wind > considerations and the cost factor. > Thanks. > Steve > > -- > > > Mark Koskenmaki wrote: > > I don't know what equiopment you use... but... here's a scenario... > > > > 20 dbm radios... 15 db panel on one side and a 32 db solid dish on the > > other.
