Below you will find the minimum dimensions for a chamber for both 1 and 3m. Now its good to take note a 1m measurement is only good for pre-compliance work not for full compliance or testing in accordance with the test specification such as EN55032.

1m Measurement Distance with a Log Periodic
The image below is for the three meter measurement distance, this is using the Log Periodic antenna or X-wing.

There is a small correction I still need to make to the above image, the table should be 1m length and 1.5m width!! All other measurements are correct.
For a 3 m UK EMC chamber structure only:
- 🟢 Budget entry: ~£80k–£150k
- 🟡 Typical commercial build: £150k–£300k
- 🔴 High-spec shielded room: £300k–£400k+
Where can I find a second EMC chamber?
