Title: AirNav ADS-B 1090 MHz Outdoor antenna with SMA connector
Post by: Wiggi001 on August 28, 2021, 01:51:15 PM
I have purchased the AirNav ADS-B 1090 MHz Outdoor antenna with SMA connector from the Amazon shop. For testing I have the aerial literally taped to a 4mtr  length of plastic pipe fixed to a high point on the roof 56m AMSL. Would it be better or does the antenna require grounding ie. a metal mast. The Airnav produces about 1100 messages/sec but does see more aircraft and at slightly lower altitude and extended range, whilst my home built 12 element collinear produces 2000 messages/sec.(The coco does not require grounding) I'll leave the station running as long as there is no wind!

Any commemts gratefully recieved.
