Hello, Sleeping Wolf
Here is a tvfool report based on Upper Middle/Walkers; you have to click on Pending to see CBLT:
If it was the ANT1005, it was probably overloaded by the Hamilton transmitters.
Gain: VHF: 26dB UHF: 30dB
Noise figure: ?5.0dB
Power Supply: AC110-120V ac 60HZ Output: 9V dc 100mA
There isn't that much difference between brands of splitters. The loss with a 2-way will be about 3.5 dB; a 4-way, 7 dB. If the bedroom TV is OK when the antenna is connected directly to it without a splitter, then a little boost might help.
I suggest a Channel Master 3412 distribution amp, which has two outputs. If the kitchen TV is further away, connect it to one of the outputs and connect the other output to a 2-way splitter for the closer TVs. If all 3 coax runs are about the same length, use a CM3414 that has 4 outputs.
