Free Microwave
Link Checker
Planning a building or wind farm? Find out whether a published microwave link passes close to your development — free, with no email address required.
1. Choose your development
Draw on the map or enter Eastings and Northings in metres (OSGB36 / EPSG:27700). Verify map positions against your survey.
A postcode centres the map; draw the actual building footprint or turbine positions.
Run a check to display nearby links.
Zoom to your site. Click to add footprint corners or turbine positions. Coordinates can also be entered directly.
Ready when you are.
Add your layout, then run the free check.
Why check the second Fresnel zone?
A radio link needs space around its direct path. This space depends on its frequency and the distance between its antennas. A nearby development can enter that space even when it does not cross the centre line.
Free check. Expert next steps.
We flag second-Fresnel-zone overlaps and links passing within 250 m of your layout. If a building or turbine is within 250 metres of a published link, we recommend an in-depth assessment by GTech. This quick plan-view indication uses the available published records.
Microwave link checks for planning
Use this free microwave link checker early in the design of a building or wind farm to identify published paths close to your layout. A flagged link is a prompt for professional assessment, helping your team address telecommunications queries before submission.
For detailed support, see our wind farm telecommunications assessments and planning and EIA telecommunications services.
Frequently asked questions
Is the microwave link checker free?
Yes. The preliminary plan-view check is free and does not require an email address.
Can I check a site by postcode?
Yes. Enter a UK postcode to centre the map, then draw the building outline or add turbine positions. You can also enter British National Grid Eastings and Northings.
Does a flagged link stop my development?
A nearby link does not automatically rule out development. Contact GTech to confirm the link information, assess vertical clearance and explore practical options for your proposal.
A link near your site? Let’s check it properly.
We can verify the link, model your proposal in detail and advise on design changes or mitigation. Speak to our telecommunications team.
