Walter Kotaba’s Polnet Communications already has a small platoon of niche AMs operating in the Chicago area. Now he has a deal to add a pair of LPTVs – one up and running, the other a DIY project – for $1.6M. That’s what he’ll pay Larry Nelson’s Nelson TV Inc. for W24AJ and W22DG-D CP in Aurora IL. Kotaba has until 3/16/10 to get the CP built, which is still in the unbegun stage. Polnet’s radio properties in the area include WPJX-AM Zion, WKTA-AM Evanston, WNVR-AM Vernon Hills and WEEF-AM Highland Park.
