Narrative:

I was working as an fpl radar controller at sector 58 in ZKC airspace. We have a difficult time talking to aircraft 4000 ft and down. This is mainly due to the radio sites being located in stl. We recently had an airspace reconfign giving us more airspace in sector 58 to the east of st. Louis (about 100 mi east). On this particular night we had icing conditions at 4000 ft and up to 8000 ft. Most light aircraft were staying down at 3000 ft. I could not talk to any of the aircraft staying down and had to resort to relaying messages through other aircraft and other controllers. This is an ongoing problem since reconfign. It can be solved by either going back to the old airspace or relocating the radio sites to accommodate the airspace.

Title: LOSS COM OCCURS WITH IFR ACFT AT LOW ALTS SINCE RECONFIGN OF AIRSPACE.

Narrative: I WAS WORKING AS AN FPL RADAR CTLR AT SECTOR 58 IN ZKC AIRSPACE. WE HAVE A DIFFICULT TIME TALKING TO ACFT 4000 FT AND DOWN. THIS IS MAINLY DUE TO THE RADIO SITES BEING LOCATED IN STL. WE RECENTLY HAD AN AIRSPACE RECONFIGN GIVING US MORE AIRSPACE IN SECTOR 58 TO THE E OF ST. LOUIS (ABOUT 100 MI E). ON THIS PARTICULAR NIGHT WE HAD ICING CONDITIONS AT 4000 FT AND UP TO 8000 FT. MOST LIGHT ACFT WERE STAYING DOWN AT 3000 FT. I COULD NOT TALK TO ANY OF THE ACFT STAYING DOWN AND HAD TO RESORT TO RELAYING MESSAGES THROUGH OTHER ACFT AND OTHER CTLRS. THIS IS AN ONGOING PROB SINCE RECONFIGN. IT CAN BE SOLVED BY EITHER GOING BACK TO THE OLD AIRSPACE OR RELOCATING THE RADIO SITES TO ACCOMMODATE THE AIRSPACE.
