RX amp required - NOT TX
Watcha.
I know I am in a minority here, but I don't want to increase my transmitter gain - if anything I tend to back it off a little. What I am trying so hard to find is an inline device which offers perhaps 9-12 dB gain for the receiver and (possibly) 3dB gain for the transmitter just to get rid of the insertion loss. Ideally I want a unity gain for the transmitter side after insertion of the RX amp.
To keep myself busy, I install Hotspots and although I have tried a selection of makes over time, the most common problem is that the laptop client can see the AP but the AP is deaf to them. As it is I use moderate gain aerials (about 8dB) and usually limit the TX power to around 50mW. This as a rule tends to mean that MOST clients that can see the AP can also be SEEN by the AP.
I don't see the point in bellowing out hundreds of milliwatts when the client is whispering back with perhaps 30, of which 20 is going into their thigh.
Already googled myself senseless and checked Ebay repeatedly. The only time I can find a pre-amp for the receiver it is almost an afterthought for some gizmo that will pump out 500mW - 1500mW and as an afterthought, increase the RX gain by perhaps 6dB
So far the only thing I can think of, is to buy one with a decent RX gain - ignore the transmitter gain totally and then just under-drive the unit so that AFTER the transmitter has been amplified it is still only pumping out around 50 - 80mW - but in the process has some 6 - 9dB gain for the receiver.
Please - I cannot be alone in wanting to improve the receiver sensitivity more than the transmitter "oomph" - has anyone found a product suitable yet?
Kind Regards
Mark
