In the last few days Sagax engineers just finished their HF direction finding antenna field trial. Some of the great workers of Sagax Communications tested one of our brand new product in a live field operation. It was a pleasent occasion not just beacause of the hot late-summer weather on the hungarian countryside. But most importantly, the HF Direction Finding antenna field trial ended up with a satisfying success. The equipment did on the field as well as in the lab.

In addition you can read further informations about the product below.
