TEST PLAN

 

The antenna will be tested on the standard “HEDVA” mount for frequencies 121.5 and 225 to 300 MHz (see Drawing). The length of the upper section will be adjusted such that the antenna will be matched on this mount and when held by hand. Measurements are identical to our standard ATP. The test procedure for 406 MHz is according to Cospas Sarsat method T.007. Issue 3
