Default Gain of 2.4GHz WiFi vertical

wrote:

Hi Group,

D-link has a vertical antenna for WiFi applications which is about a
foot long and operates at 2.4 GHz with a stated 7dbi gain.

Since the antenna is a vertical, I thought that the best low-angle
radiation is 5/8 wave for verticals, anything longer would put the
lobes higher and would result in a lower low angle gain.

If this is the case then the antenna should only be about 3.5 inches
long. ?

I am going to check, but I bet the true antenna is only about this
lenght and the rest of the lenght is the plastic, so the appeal is
bigger is better.

Any thoughts on this?


Collinear??
