Hey guys.. So I'll be getting my tax return soon.. I really wanna finish making a good - more perminent roof top or pole top unit.. I just can't decide which will be best .. An 8-9dbi omni antenna like the two Gramm was using.. Or if I should buy two circular polarized 8-9 Dbi antenna like this one
I guess what's confusing me is that they both are a 360 degree antenna correct? In which case. Will they be pretty equal? I'm looking to get 15k or so feet In all directions .. The higher Dbi the more range but worse bandwidth.. How does this stand true when you have an antenna that already puts out a 360 degree donut of signal all the way around it.. Is the donut of signal still there.. Only much thinner when you go up in Dbi? Only speaking of circular pol- and omni directionals.
So which one do you think can provide the best distance while still keeping the most amount of 360 degree signal? And at what Dbi does that 360 degree really start to suffer? 9-10dbi?
