After snapping our VHF aerial with too large a flag at the recent Harbour festival (!) I need to buy a new one, but which one?
I understand that the higher gain in db, say 6db will give a narrower more direct signal, like a focused torch beam but a 3db gain will produce a broader although less strong signal less affected by the rolling motion of the boat?
Is this correct?
I would have thought that the taller the aerial the better but looking at the narrow radiating pattern of the higher gain 2.4M aerial I'm not now so sure
Narrow beam or broad beam?
Any brand to avoid, is more expensive necessarily better, I was looking at a Glomex in Force 4
Any input very welcome
Thanks
