Hmmm... I found this...
Excerpt from Encyclopaedia Brittanica...
"obelisk, tapered monolithic pillar, originally erected in pairs at the entrances of ancient Egyptian temples. The Egyptian obelisk was carved from a single piece of stone, usually red granite from the quarries at Aswān. It was designed to be wider at its square or rectangular base than at its pyramidal top, which was often covered with an alloy of gold and silver called electrum. All four sides of the obelisks shaft are embellished with hieroglyphs that characteristically include religious dedications, usually to the sun god, and commemorations of the rulers. "

"Other peoples, including the Phoenicians and the Canaanites, produced obelisks after Egyptian models, although not generally carved from a single block of stone."

Of course, this does not address Canaanite recognition of sun god in particular, whether their obelisks had sun god symbols on them, etc.
