Hi,

I am wondering if i can use different antenna configuration on draytek products such as a AP903 or 2860AC router.

so in plain term i have 2 questions.

can i use different antennas on a single device i.e. a omnidirectional antenna and a unidirectional on a single device ?

also

is it possible to use extension cable to allow variable locations of antenna, i.e on a 2860ac could i extent the 3 antenna and place them in different locations to get betted coverage? or would it be feasible to extend just one of the 3 antenna and leave the other 2 on their normal position ?

Any tips would be welcome...

Thanks

Ian

It's not a good idea; they are generally paired for diversity. It may be a usable compromise for your particularly circumstances.

As admin says, there are reasons for the antennas being as they are*. I'm not sure how the diversity calculations are done when using two or more identical antennas (btw why the apostrophe?) - but if using a mix of directional + omnidirectional one can imagine that things could get confused....

If using extension cables bear in mind the cable attenuation - https://www.digitalairwireless.com/articles/blog/signal-loss-in-rf-cable-what-is-the-numbers (other websites are available).


* Interesting that the 2926 required 4 aerials whereas the 2927 only has 2

thanks for this, it is very useful info.
