Mikrotik Wireless long distance

304km Wifi record with MikroTik
i found this news from mikrotik forum, here the news.
On 16-06-2007, we (CISAR, a radioHAM italian association) have realized a 304km link (about 100km ground and 200km sea surface), between Amiata mount (1734asl) and Limbara mount (1300 ca asl).
We utilized a pair of wrap board (but they will be replaced by a new RB532 soon), a pair of Ubiquiti XR5, and a pair of handmade antenna (120cm satellite dish for the surface, and a bronze ball-bearing extracted from a bus).
The signal received on both end was from -58dBm to -62dBm, bitrate between 12 and 48Mbps, CCQ between 70 and 100.

On the moment i'm writing, this seems to be a distance world record (the precedent was from "Politecnico di Torino" on Italy, 295km).
The people which partecipate on this WR:
Amiata Mount
- Giuseppe IW5CGM (CISAR president);
- Antonello IK0TCL
- Mirco IZ3HAD (me)
Limbara Mount
- Natale IW0UIF
- Paolo IK0PCJ (antenna's constructor)
- Mauro IK0YUK

New Product From RouterBoard.com

RouterBOARD 433AH
The RB433AH is a more powerful version of the
standard RB433. The 128MB DDR will be capable
of supporting new RouterOS features coming. The
microSD slot supports an additional memory card that
can be used for a Dude database and other features
to be announced in during Spring ‘08.
The 680MHz Atheros MIPs 24K CPU, that can
be overclocked to 800MHz, with a 64KB/32KB
instruction/data cache is probably the fastest CPU
used in low cost wireless access points.
The three Ethernets and mpci slots give you ample
data interfaces to put the big CPU power to work.
The RB433 and RB433AH replace the RB133 and
RB333 positions of our product line.
