scanner outdoor antenna

Many outdoor scanner antennas advertise wideband coverage from about 25 MHz up to 1,300 MHz. Other models focus on specific VHF and UHF bands — common examples include 136–150 MHz, 144–148 MHz, and 430–450 MHz.

Common connector types for outdoor scanner antennas include UHF (SO-239) female, BNC (commonly BNC-male or BNC-style plugs), SMA-male, and NMO-style mounts/contacts.

Typical mounting styles include base/mast-mounted antennas for permanent installations, magnet-mounted or trunk-mounted mobile bases, hole- or L-bracket trunk mounts (including NMO-style options), and bracketed base installations for fixed mounting.

Many outdoor scanner antennas list power ratings around 200 watts, with some wideband designs showing up to 300 watts maximum (many models note lower transmit limits for specific uses such as CB).

Fiberglass base antennas in this set list maximum wind-speed ratings ranging from about 90 MPH up to 135 MPH, depending on the model.

Some mobile and trunk-mount antennas include preinstalled coaxial cables. Examples from this set are a 10 ft RG174 with an SMA-male connector and a 17 ft low-loss RG58/U cable with a BNC-male connector.

Superdiscone scanner antennas here list an SWR of less than 1.5:1 and advertise wideband reception across roughly 25 MHz to 1,300 MHz.
