Connectivity and antenna

USB type A connector to connect directly to the computer (no cable required, USB Powered)
SMA female antenna connector. Requires an antenna with SMA male 50 Ohm (not included)

The DV4mini requires an antenna. It must not be used without an antenna. You can use the commonly available ‘rubber ducks’ with a SMA connector like the ones used with walkies. The DV4mini must not be connected to a high Yagi or similar antenna.

If you use a physically adjustable antenna, be careful that when you adjust the position of the antenna you hold onto the base and not the housing. Otherwise you may damage the SMA connector.

Le meilleur Hotspot Numérique
Un excellent dongle : révolutionnaire et très polyvalent pour tester chez soi les modes numériques . Il est également possible de booster sa réception et sa puissance d'émission avec un mobile philips de récupération de type PRM8020 ( modifications pour les Oms experts et a vos risques ) . Merci à PRS pour le sérieux dans ses expéditions et dans le suivi des commandes . 73's de F1MIJ Pascal
