When you say east would it be by Lawson Crescent and the rail line to the concrete plant?
If so it would be the new Rogers tower that had the consultation notice in the paper about 5 or 6 weeks ago about going up in that area.
If it is the one, it went up fairly fast. I guess being in an industrial area there is less chance of any opposition.
I did see that the bare monopole tower that sat further south on Kenaston (owned by SBA communications and was built a few years ago in anticipation for Wind coming to Winnipeg) is probably the one that Dan is talking about as it now has antenna's hanging and an electronics package in the compound.
It is conceivable that MTS has now leased space on the tower thus the tweet that ARKAY1_SID posted.
I can think of at least 4 more that SBA has in Winnipeg so I wonder if MTS will also be doing something with them for coverage upgrades.
