I have a very simple set up which gives me an interesting aircraft monitoring system around 12 miles from Heathrow.
Reading up I see it is often recommended to snip the top off a supplied aerial if it is too long, thinking this to be a simple idea I unscrewed the aerial from its base. With no effective aerial now connected to the device it was still picking up 8 aircraft on Skyview.
At this point I wondered if there was any value in snipping a few mm off the top of my present antenna, left it for now.
Appreciate outdoor aerials must be ideal but wondering about indoor aerials when mine still worked without the whip screwed in.
