With huge amounts of said subject, I decided to do surgery on my 3-4 day old system. The antenna fix to the CM15A.
I did the tip removal and soldered enough copper wire to the tip of the antenna to make it 9.5" overall.
Seems like it made a HUGE difference. Although I didn't do a real scientific test.
There maybe be a xmit difference between the ActiveEye and the Security MS10A. But the MS16 seems a lot more solid since the antenna surgery.
The MS16 was real bothersome on the perimeter of the house and I fiddled with them all afternoon. Didn't try the Security modules before the alteration, but the MS16's were dropping signals(it seemed) before hand. This was approximately 25-30'.
The 16's started behaving so good after the fix, that I tried a MS10 and a DS10. They worked rock solid well out to 85-90 feet in 3 direction. Didn't try the fourth direction because it was dark, I's in shorts, and that directions is a little overgrown.
Real happy so far, except a nice antenna from the factory would be......; still in a learning curve tho.
I would like to thank all the experienced hands here, Tuiceman, X-10, and I'm real sorry but I don't know all the names, but all the information posted has got me and I'm sure countless others headed in the proper direction.
I put a passive coupler in and all systems go. I haven't got the filters in yet,but soon to help in the reliabilty.
Thanks to all of you and a great big HELPFUL.
