Hi.

I'm having a bit of trouble trying to work out what will work well for the following.

At my place i have one senao ap connected to a 15db omni. Now I'm having issues connection one of my clients to this, even though he is only about 1.5km away.

What i want to find out is this. What are the pros and cons of having 3 or 4 yagi, panel or sector antenna vs one omni? I know that having 4 antenna means 4 radios, and that would mean 4x the power over 360 degrees, also this should mean only a quarter interference per antenna vs the omni.

But all that aside will it improve my signal strength to the marginal clients? even if the gain per antenna is the same gain as the omni?

O, and will it be OK to put all 4 radios in the same water proof box, and what about all the bleeding signals!!!

Any experienced or not so experienced advice will go down very well.

Well... Could i have them all the same? And what about the channels, all diff?
 
:eek: I'm not even gonna attempt this one.... I'm too damn tired.
 
:( Please, I promiss to listen to everything you say and make you proud!!!

Show my your ways o great one.

Im feeling the power of the pillows 2...
 
Do another search in this same forum, for the word Omni!
 
yagi's are directional... omni's arent...

you'd need a yagi on each side... pointing the right way.. no point one guy having a yagi and being able to send his signal strongly when the omni on the other side can barely transmit a strong enough signal for the yagi to receive
 
Omnis do have a place BUT if you dont need to radiate a 360deg pattern, then dont use them. Omni's are used due to cheap and nasty solutions.
Wifi uses contended bandwidth ... so there is a max throuput - ALSO - its only as good as the worst link. Rather invest for best Links, not best coverage.
 
Good advice, Thanks

You will be glad to know that i have ditched the omni and make a plan for the mean time...
 
Besides, those 15dBi omni's that everyone is running around with, only show about 10dBi of gain when put in a testing chamber.
A bit of a waste of time and money really :)

Use Sectors or directionals instead.

Wow ... every 3Dbi's you lose you 1/2 the signal strength :eek:
