Hi There, at the moment, I am getting on average 60 miles all around, Though I would like more, It is on a 12 ft pole,
Is the only way to get more range is to put it higher and higher?, though I have no idea how I am going to do that!.
Many Thanks John

hi john
it all depends where you live location location location i get about 60 miles with my supply aerial on my window sill, i personally think the supply aerial is brilliant and when your out mobile its out of this world
height is might is what they about aerial and a good earth keeps away static/noises.
i will say trying moving you aerial you will be surprised at the difference it will make.
all the best from pat

Short answer is Yes
Long answer is that it may be possible to improve range in some altitudes by using an antenna with more gain or a different polar pattern.
However there ain't no such thing as a free lunch - so what you gain on the swings you will inevitably lose on the rounabouts.
EG: You may use an antenna that has better gain at , say, 15-30 degrees above horizontal - but may the sacrifice sensitivity in the overhead.
All that said - the biggest limiting factor is the radio horizon from your particular location.
If there is high ground in the way - then the only way is to get your antenna ever higher.
Here I am 400 feet amsl - I can "see " just over 300 miles to the east straight up the Channel - right into Belgium...but to the west 35-40 miles is about the average.
