I know why most of the guys depending on where you live get poor performance.
I was away on holidays last week in the US for 10 days and on my drive back was checking the elevation using my laptop and Streets and trips 2006 with the gps locator.
I noticed that in the Fort Erie, Niagara, St Catharine, Welland, Grimsby, Stoney Creek area the elevation above sea level is only 140-180' on average.
Oakville was also low around 280' in elevation on average.
Mississauga went up into the mid 300'
Along the 401 from 400 to 404 was 410-460'
Sheppard and 404 was 460'
404 and Finch and Steels was 460-480'
In Markham around Mcowan and 14th where my home is reads 532'.
I know as you head north of Hwy 7 the elevation gets even higher.
I bet at my dads house, he is a good 60 to 80' higher than me that is why he is able to get such strong signals from Buffalo with a 4221 and its not even mounted 18' off the ground.
Last night check and WB 49-1 is stil coming in strong. I know once the weather gets warm above 70'+ even if its not a dx day I can get a good lock on WB49.
Elevation makes a difference. Ohh only if everybody was as lucky as tricky to mount a impressive tower like his.
