• grip-dip dipmetre

    From bp@21:1/5 to All on Tue Dec 6 15:04:03 2022
    Hello

    I am French and I use google to translate because I do not understand
    English
    I am going to buy a grip-dip /dipmeter but there is something I would
    like to clarify
    On an unconnected antenna with a choke how can we measure its resonant frequency?

    Is it just approaching the choke dip grip or is it necessary to feed
    the antenna with a signal?
    if so what type of signal?

    thanks for your advices


    Bonjour

    je suis Francais et je me sers de google pour traduire car je comprends
    peu l'anglais
    Je vais acheter un grip-dip /dipmeter mais il y a quelque chose que je
    voudrais pr�ciser
    Sur une antenne non branch�e poss�dant une self comment peut on
    mesurer sa fr�quence de r�sonnance?

    Est ce en approchant le grip dip de la self simplement ou est il
    necessaire d'alimenter l'antenne avec un signal?
    si oui quel type de signal ?

    At the antenna connector or coax feedline make a coil of about 5 turns
    and connect it to the antenna connector and grid dip that.

    Okay Ralph
    I will apply your solution later I think to use a nanovna

    The nanovna is much better. You can sweep a large gange and either use
    the SWR or the return loss function.
