A well-assembled BNC can be used in a lab environment from DC to about 1 GHz. The BNC is very easy to mate / unmate, and it is not horribly expensive. However, a test antenna is moved around during use, and puts stresses on the attached cable. Since you want the antenna / cable assembly to be very reliable, I wouldn't recommend using a BNC beyond about 30 MHz. Better results will be had if you use a TNC or an N connector. If the antenna is being carried on a mast carriage, then you should consider proper cable support to keep the cable weight from hanging from the antenna connector.
