I had some airband modelling carried out of the airband transmitters at the airport carried out for my address and found that I am far enough away from the 20m hill between me and YBBN tower for good reception. Tried with basic airband radio standing on outside deck and all works very well.
To provide feeds, if required, what antenna is preferable? I was looking at a discone.
And, what would be an adequate receiver/scanner that I can use to connect into the network, as my old Pro2021 a bit old?
Any advice would be appreciated.
Your Pro-2021 will do fine. As far as antennas, something narrower in bandwidth than a discone will do better, in general. Tune a ground-plane antenna for the middle of the band and you should be fine. But if you're interested in using the antenna for other things outside the aviation band, then a discone is fine. Experimentation is key.
