W288CE

Mike Fitzpatrick's necrat.us is now displaying the W288CE antenna at the WPKZ-AM 1280 site in the northwestern part of Fitchburg, MA. (He doesn't include the call letters; I got them from fcc.gov.) The question is: I've listened to the top-of-the-hour station IDs recently, and so far, I haven't heard them say anything like "WPKZ AM&FM" or "WPKZ-AM, W288CE-FM". Has WPKZ commenced broadcasting on their FM channel yet? Also, it seems curious that they didn't install the antenna on one of the 1280 towers a la WNNW in Lawrence. And the terrain out there seems to cause thie HAAT figures to vary widely: from +209 meters to -60 meters.

Height above average terrain. Fcc.gov has a little feature that displays the "effective altitude" over 360 degrees.
 
i was riding through Marlboro today and heard it on 105.3 wwlli out of providence turned there hd off or it was damaged inthe flood so it came in really well hope this helps

It's solid down here 20 miles south of Boston with my APS-13 aimed that way. WWLI's HD being off certainly helps.

Because it doesn't have a call sign yet. W288CE is the callsign for 105.5. The 105.3 station, when the license to cover is issued, will have a W287-- call sign. (105.5 is channel 288, 105.3 is channel 287). When it does, I will modify it.

Also, it seems curious that they didn't install the antenna on one of the 1280 towers a la WNNW in Lawrence. And the terrain out there seems to cause thie HAAT figures to vary widely: from +209 meters to -60 meters.

Simple. Cost. A lot less feedline. There is no need to have a FM isolator put on one of the tower bases. I believe if you mount something like this to a AM tower, you have to demonstrate that the installation does not interfere with the pattern and/or the tower's electrical charecteristics. This site is high enough that a roof mounted FM antenna will cover a good amount of terrain without much issue.

Aren't WPKZ's towers self-supporting? If so, side-mounting an FM antenna on one of them could present structural problems in addition to the isolation problem that was already mentioned. If they can get the signal out without having to deal with such issues, everybody and everything will be better off.
