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.
