Postcode Link Checker. 

Check your link distance "as the crow flies" and terrain obstacles between the link,

 just enter the two point to point postcodes (UK) and hit enter.

 

Adjust antenna height each time to gain "line of sight".

 

This system will give you a good idea of the distance point to point and if you have any

obstacles in your way, it can also provide an insight into the technology you can consider

for a link such as RF "near line of site" which can stretch to 20k, Laser for direct LOS or

Leased Circuits if we cannot move the mountain (this does not replace the need for full

surveys when looking to make a purchase).
