  • 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 préciser
    Sur une antenne non branchée possèdant une self comment peut on
    mesurer sa fréquence de résonnance?

    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.
