Osnovni podaci za izradu portable multiband antene  za tri nam najdraža banda !

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!

Antena napravljena u svrhu portabl QRP aktivnosti
