Yes exactly, It is Male connector.

I have connected the antenna to this port for AM690 and AM730

I have set the Quadrature in HF mode tuning but still, I can not receive any channel and I am hearing only noise.
Thanks so much for your help.

Any suggestion?

Ok,
I have only noisy sound when I set it to AM 690 (CBC) or AM 730 (Vancouver Traffic) and I can not hear any vocal sound.
Do you know what is my problem?
