The antenna is fine. Works as advertised. Mine has been in use since 2016 no issues.
Review: ... cannot find the correct adaptor sp it is basically useless. - It doesn't accept the regular male coaxial end and I cannot find the correct adaptor sp it is basically useless.

Nothing wrong with this antenna. a N connector is the standard for vhf/uhf and if you don't have a n connector male the adapters are readily available even here on Amazon. The antenna is fine. Works as advertised. Mine has been in use since 2016 no issues.

### ⭐⭐ ... cannot find the correct adaptor sp it is basically useless.
*by D***T on October 20, 2015*

It doesn't accept the regular male coaxial end and I cannot find the correct adaptor sp it is basically useless.

### ⭐ Review
*by P***N on May 19, 2021*

L’antenne devait aller jusqu’à 450 mhz, celle reçue s’arrête à 435 mhz. Il s’agit donc de la version européenne et non de la version US. Annonce mensongère, cette antenne ne me sert donc à rien.
