Deerslyr1,
DoubleUp did a fine job on the the Driveway Patrol he modified for me. It works great with the antenna. He tested it to 150 yards as I recall and it worked. I've only used mine at 60 yards. Though I haven't had a coyote hit the bait while I was hunting, I did have a possum awake me when it passed in front of the sensor.
As he mentioned, I use a volume control device to adjust the volume up or down as needed. I found it on Ebay. DoubleUp wired up an earbud jack to the receiver. I then plugged in the volume control to the jack, then plugged in a set of headphones to the volume control (earbuds were annoying to keep in place) and now I can control the sound to a suitable and comfortable level. I can sit and snooze while in the chair at the shooting table, or relax on the bunk with the headphones on. When something hits the bait, it alerts me through the headphones. It's a pretty neat system. It works, and it's quiet.
DoubleUp also used a box to mount the transmitter in and made it easy to mount to a tree
or post by means of a buckle strap. He also added a bit of camo well. Maybe he can tell you
more about the box he used. He cut out an opening for the sensor. The unit is protected
from the weather fairly well except for the small opening where the sensor shows through.

Headphones - these are cheap and all that's needed.
As to moving your bait site further out, you will need to be able to see well and get on a target rather quickly. In my case, I am using infrared lights mounted at the bait site (up in a tree) and a night vision scope. At 60 yards I can see extremely well, even 100 yards would not be a problem for illumination. The 5X magnification of the night vision scope is great at the 60 yard range. I have considered moving my bait site to about 135 yards in order to get the coyotes further from the cabin to hopefully cut down on any chance of spooking them. Illumination won't be a problem (infrared lights again) but the limited 5X magnification would cause me to have to be much more precise with my aiming. I haven't moved the bait site yet but am considering doing that maybe next fall just to see how it works.
Hope this helps and gives you a good idea of how the unit looks and works.
Oh, one other thing some of you may find of interest is the Nite Site night vision scope. Seems we predator hunters are always looking for a better mouse trap. This unit is manufactured in the UK but can be shipped to the US. To my understanding, it costs somewhere around $945 US for the NS-200, not cheap but very interesting. The clip below shows the NS-50 (cheaper version and limited in range) in use on rabbits with an air rifle, but I am eyeing the NS-200 which has much greater range.
This device will allow the use of a day-time scope and also allows greater magnification. For baiting purposes it might not be too bad, but might cause a bit of a problem if moving about the fields and woods since it has wires connected here and there and also a battery back to carry. I'm currently in contact with the company and inquiring more of the device to see how well it might work for my application. I don't have the funds to purchase this unit (yet) but it never hurts to keep a sharp eye out for something new that might work well.
Just thought you might like to see, and if anyone has experience with this scope or knowledge of it, please share it. Here is the YouTube link, and there are other clips on YouTube as well pertaining to this scope.
