Basic data for making short antenna for our most favorite bands !     

Trap - Koax na d = 30 mm                                                              

Koax RG 58AU

trap 14.040 MHz cca 8 zavoja/turns                                       
trap 10.140 Mhz cca 10 i 1/2 zavoja /turns                                   

Koaxialni trap je izrazito " oštar " ( 20-50kHz.)

Trap je potrebno fino ugađati i nakon pakiranja u termo plastiku ! 

Dip metar ili MFJ-259 je obavezan alat za izradu-

trapa a kasnije i same antene !

Coax trap is extremely "sharp" (20-50 KHz).

It is necessary to tune trap even after shrinking of thermo-plastic!

Whole work on tuning is senseless without acurate GDM or MFJ259!
