HF – 70cm Multi-Band Mobile Antenna. The 40M, 15M and 10M coils come with the antenna and are installed in the photo to the left. The 80M, 20M, 17M coils are optional. Each HF band is tuned by sliding the tuning stubs. 6M/2M/440MHz tuning is pre-set.

Mobile Mounting: The UHV-6 was designed to be lip mounted using the CP-5M or HD-5M (coax included). If you already have a coax cable assembly, use the RS-730 or RS-840 lip mount brackets. Providing a good ground connection for the antenna is important for good SWR. The set screws that hold the lip mount to the door must penetrate the paint for grounding.
User defined set-up: Without any of the HF coils attached, the main mast of the UHV-6 is a small 6M/2M/440MHz triband antenna. YOU choose which coils to attach, in any combination.
For example: If you want a 10M/6M/2M/440MHz quad-band antenna, then only add the 10M coil to the top of the main mast. If you want a 40M/20M/6M/2M/440MHz antena, screw the 40M coil on the top of the main mast and the optional 20M coil to the side and you have a 5-band antenna.
At the top of the main mast there are six threaded sockets where the HF coils can be attached (5 on the side, one on top).
Due to the weight, the UHV-6 was originally designed to hold up to three HF coils at a time while mobile. You can add more if you are parked. When mobile, a guy line is recommended if more than three coils are attached. Due to the weight, the 80M coil should be attached by itself or the antenna guyed.
