ADS-B Vertical Outdoor Base Antenna (978 MHz UAT)

  • $159.95

Please Note: The 978 MHz service is much less utilized than the 1090 MHz service. Please make sure that this is the model you actually need.


Gain:  8 dBi SWR:  1.5:1 or Less Pattern:  Omni-directional
Wavelength:  Multiple 1/2 Tuned:  978 MHz (UAT) Band:  ADS-B ES
Connector:  N Female Cable:  RG8X Cable Length:  24 Inches
Height:  57" Width:  1 1/4" Weight: 2 lb 2 oz
Wind Area:  0.50 Sq Feet    


Ready Made:  There's no assembly necessary, or extra mounting parts needed.

Tuned for ADS-B UAT:  Each antenna is designed to be used for the ADS-B 978 MHz UAT (Universal Access Transceiver) band, using any receiver capable of receiving 978 and connecting an external antenna, such as: Dual XGPS series, and Garmin GDL 50 & 52 series. This antenna can also compliment a system setup for linking to an online virtual radar network, such as: ADS-B Exchange, PinkFroot's or FlightAware. (Please note that we also have a version tuned for the more common 1090 MHz ES service.)

No Ground Plane Needed:  A metal ground plane is not needed with this design.

Enclosed Elements:  The actual antenna elements and feed point are sealed inside a UV resistant plastic radome. No need to worry about corrosion on the elements with this design. This design also helps control friction induced static, which can be created by wind and dust.

Weather Resistant:  Having the elements and feed point sealed in the radome allows the antenna to be very resistant to weather and other environmental damage. This antenna is strong enough to withstand an ice storm, and will also do well in a shoreline environment.

Brass Elements:  The inner elements are made from brass, which is a better element material than stainless steel.

Narrow Bandwidth:  The bandwidth for the antenna is fairly narrow, which can help to eliminate intermod problems from adjacent strong signals in urban areas.

High Quality N Connector:  Instead of the usual UHF connector that's included with most antennas, this antenna includes a 50 ohm female N connector, on the end of a small cable pigtail. N connectors are more water resistant and handle high frequencies better. Note: Due to the high frequency that these systems operate at, and the potential losses that can occur through cable, it is highly recommended that at least a full RG8 size coax cable be used, for significant lengths.

Includes Mounting Hardware:  Price includes mounting clamps to allow attaching the antenna to any standard 1 1/4" to 1 1/2" mounting mast.

"Been using the 1090ES and 978UAT outdoor antennas now for about a year.  They have been through heavy winter ice, large hail and high winds, rain, and high heat. The antennas are outperforming anything I’ve used previously."
