Hi,
I'm wondering if I'm to design a link with SD configuration using XPIC. what factors i should be considering. I know when planning for SD link i should consider higher SD improvement factor by changing antenna heights but is there any other factors i should be aware of upon planning the link?

Any information on the topic will be highly appreciated.

By the way, sometimes if i wanted to get SD improvement factor close to 200, i have to make the different between main and SD antenna heights something around 30 M. is this is normal to have 30 M between main and SD antennas? usually i see only 10-15 M for the old installed links.

Thanks.

It is very normal if the region is duct prone. In many parts of Nigeria specially the Delta Region I designed SD links with XPIC and I have to use very tall towers with almost 30 meter spacing to achieve the required reliability and performance .It was in 7/8 GHz band with CCDP configuration. Hope it helps.
