Re: show your mobile antenna array
You want to be sure to fuse AT the battery (both
positive and negative leads), THEN power the switch etc. I use
50A self-resetting circuit breakers. This protects the line
used to power your gear, not the radios (use the appropriate
fuse AT each radio). You want to use both leads for maximum noise
reduction (the battery is a huge capacitor) and lower IR^2
losses (not returning through the vehicle body). However in a
new vehicle, which may measure alternator load, you want the
negative at the chassis ground point so it can be included in
the load analysis of the vehicle computer. You want BOTH leads protected from accidents; if the positive was shorted or consider what could happen if the vehicle ground lead disconnected; all the current (of the starter for example) would pass through your radios; definitely a 'not good' situation. (You also want a larger extinguisher, if you're ever planning on putting out more than a cigarette or small campfire; they go quickly and change it at least annually, the road vibration packs the powder down hard making it ineffective.) 73,

show your mobile antenna array
ja moran <analon1@...>
here is the antenna array on my Ford F-150 To avoid drilling holes in the cab roof, I created a platform or rail behind the cab that I punched 3/4 holes for each of the NMO mounts. all the wires go over to the passenger side and go under the truck where the wires loop incase the truck bed needs to be raised for service, then enter the truck. I put some tape over the wires where they enter below the rear passenger side back door. I also ran an 10 gauge wire from the battery to a master switch then to a fuse block where every radio or accessory (dash cam, backup cam, front camera, PA amplifier, radar detector and several radios) the PA amplifier is to let people know their vehicle needs service when their turn signals are not working.

That sucks. He is the reason I bought so many of their scanners. I hope they bring on some one to try and fill his shoes.

Re: Happy Thanksgiving
Jeff Kenyon
Happy Thanksgiving to everyone as well. I am in Louden County, Tn until Saturday and had read that the TACN talkgroups in this area are supposed to be encrypted but there is quite a bit of activity in the clear. Also, on the way down and back I stopped in Detroit and had some time to monitor the MPSCS TRS in Michigan. I used to live there, and the MPSCS is one of my favorite systems to monitor, and I’ve always wanted to try it with the BCD436HP!

Re: Antenna Recommendation

Same here for the D130J. I have had one for years 15-20 in my attic, with a string of Uniden receivers--waiting to buy an SDS200 if I can find one on sale on Black Friday or Cyber Monday--works great. Even in the attic it easily has provided a 30-50 mile range.
