@ Casser
I think you never compear this 2 ant.
The visio are desing for TX and that mains transmit, the transmit freq are higer so for TX recieve he have not the max gain and radiation pattern.
TX Gain are 42,5 dB on 14,25 GHz
RX Gain are 41,8 dB on 12,50 GHz
10,70 GHz must be arround 39 dB if you see the lin.pat.
This main the dish are from 10,7 to 14,5 GHz
and that is a big range.
next - 3 dB pionts are for TX 1.1
and for RX 1.3 dB
So antenna are 100% desing for tranmiting signals
Fibo makes in the old day's 2 models 1 grey for RX and a Withe model for TX make a send a photo asap.
Viosiasat can be a nice dish bud not a 100% good desing for recieve as most users here do.
Next are that visiosat have not a orginal clamp for this dish for a RX LNB
as told me by Visiosat on the IBC here in Amsterdam last year.
