Jeez, finally someone noticed!

I've been wondering if I was the only one that ever listened to Disney on 1290, and I live just south of El Cajon, not in the IE! They were my preferred Disney station, even though KDIS and KMIK both have much better signals at my house, because they didn't run IBOC and had analog audio to at least 8 kHz. Last I looked a few days ago, their wikipedia page and Radio Disney's site and wikipedia all still said 1290 KKDD is Radio Disney.
They had dropped disney a few months ago, switching to a simulcast of 99.1 KGGI. I found this out while on a bus en route (via Santa Ana, etc) to an appointment at LLU dental school. I had been listening to 1110, switched over to 1290 cause 1110's signal was dying in the bus, then dozed a while. (I had stayed up late the previous night, and the signals were just barely cracking the noise level on my PL-606.) When I woke up hearing something on 1290 that definitely was NOT Radio Disney, I nearly thought I had died and gone to hell! What happened to my RD music?!? I was wanting to listen to them on my radio to keep my mind off the dental work. Data service is nearly non-existent in the dental school on my phone. I did have music locally on my phone, but I really wanted to use the radio and save my phone's battery.
BTW when I went again a few weeks ago, they had flipped to Good News Radio. I consider that an improvement over a KGGI simulcast, but I still want Radio Disney when I go there.

(Are rbrucecarter5 and I the only ones on these boards who sometimes like listening to Radio Disney?)
So, for next time I go there (scheduled before Memorial Day weekend, pending my full recovery from a cold / sinus illness / something that's gotten to me the past week and a half), anyone got suggestions on how to bring a usable signal from KDIS inside the apparently heavily shielded building? For reference, 1290 KKDD indicates 65/25 outside the building (on the lawn) on the PL-606. The strongest signal, 1240 KEZY, indicates 76/25 outside and often 15/00 inside with no discernable signal. The Disney target, 1110 KDIS, indicates 47/25 outside, and naturally has virtually no detectable signal inside (except in a few spots that I may not be near).
What antenna would I need to buy or construct for under $30-50 that would fit in my backpack, I could set it on my lap while in the chair being worked on (preferably a different footprint than the Select-A-Tenna - something like a ferrite sleeve loop, for example - basically shorter and wider), and bring in a usable signal from KDIS (at least 15/07, preferably 24/25 or something like that) into the building and inductively couple it to my PL-606? I'm guessing it would need at least 30-50 dB or so of gain too bring in the desired signal.
