I have a new WiMax 2.3Ghz broadband service that has marginal reception. As the frequency 2.3Ghz used is close to WiFi I am thinking I can use a cheap WiFi yagi instead of a much rarer (and expensive) 2.3Ghz yagi to improve reception.
I'm aware that I won't get as much gain at 2.3Ghz versus 2.4Ghz as the antenna won't be perfectly tuned but I believe yagi antennas are somewhat tolerant to being used a little outside their tuned frequency.
Can anyone explain or point to more details on yagi performance outside its tuned frequency so I can work out if I should DIY a 2.3Ghz tuned one? I'm OK to lose 3dB of gain but not much more.
Thanks for the input.
