Re: Using 5.0ghz Antennas with 2.4ghz Access Point.
I the antenna is specifically for the 5ghz, it will not work on the 2.4ghz. You need to make sure you replace those with 2.4ghz antennas. The gain is really a reference and I really don't change that unless I have WCS/NCS.
The 5ghz antenna is tuned to handle frequencies in the 5ghz range. Using them on 2.4ghz APs, does not mean that the AP will not still radiate signals from its internal radiator (IR). However, as the antenna will filter out the 2.4ghz frequency, there will be no gain added to the signal, hence the EIRP will be much lower due to considerable loss.
