Mike VE7KPZ has ordered the 2 x HAMwan CPEs required to setup the point to point network link between the VE7EGO repeater site and Brad VE7WBM's QTH. This will facilitate an alternate internet connection for the mountaintop shack.

While many HAMwan folks are recommending the MikroTik RBLHG-5HPnD model for it's great receive performance (due to a large dish), this unit is not really meant for a windy mountaintop repeater site.

Instead, Mike has chosen the latest generation in the MikroTik SXT line, the RBSXTsq5HPnD model (front/back):

This CPE has a little lower gain, but shoots out a bit more RF power (if needed) to overcome it's gain deficiency. Survivability of this unit is much higher for windy locations with an upwards of 200 km/h wind rating.

Check out the brochure here.

A pair of SXT sq5 HP units is advertised to be good for upwards of a 12 km link, but we only need to do 4 km as the crow flies from the mountaintop to Brad's QTH. We'll also narrowband the RF transmission channel to both preserve spectrum but also achieve a more resilient connection by focussing the CPE's RF power on the smaller bandwidth.

Brad's YL will also be happy with a lower-profile "dish" mounted to their house.

The units were ordered from BC supplier Solimedia. We look forward to their arrival so we can get to work setting up the link.
