I'm getting great reception with my soda can and I won't be experimenting with cans for the time being. After doing so much work building antenna poles out of bamboo and lumber I'm going to abandon those and go with a roof mount. My reception is blocked to the northeast by the house, even though the antenna is 14 feet off the ground. Here's the roof mount I will buy:I have tried Cantennas with both higher and lower diameters than 66 mm., from as low as 3/4" (20 mm) dia copper water pipe with cap, to 10 cm dia can. Lowering the dia below 66 cm reduces range. Increasing the dia above 66 mm does not show ant noticeable increase, almost same as 66mm Can.
No harm in trying a 7 cm dia beans can, provided it is cut to 69mm height, like pepsi/coke can.
Please see two (2) pictures below.

I don't remember if I asked you if it's possible to feed two receivers off the same antenna using a coax splitter? If so, which one should I buy. After I put this antenna on the roof I don't want to add more antennas up there if I can help it!
