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.

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,

If we fail to learn

A headache rack also makes a good antenna mounting solution on a pickup.

"the PA amplifier is to let people know their vehicle needs service when their turn signals are not working."
You can sell them Blinker Fluid. January is "change your blinker fluid month"

many years ago my wife took her vehicle to a now closed Firestone shop for an oil change. the mechanic noticed that her left rear blinker was not working and offered to do...and i’m not kidding...a “blinker system diagnostic” for only $29.95! she opted to take a chance andcjust have the bulb replaced. 👍

Here are a view pictures of My Mobile installation I will add a couple of Notes The SDS-100 Fits into a Mobile Mic holder , Do not mount it close to the Vents the Heat and Cold will keep the battery from charging properly Also I use a Motorola Amplified Speaker No hiss because I can turn down the Viol on the SDS-100 Sounds great and loud
Wishing Everyone a Happy , Safe and Healthy 2020 Happy Scanning
Don KA9QJG
Not sure the pics will show until I post the 4 ant in the middle are for Direction Finding
PS And Yes I should know better than to mount Equipment on the dash like this in case of an accident. It is secured with very heavy industrial type Velcro..

Come on, this is a joke, right? You’re putting us on, yes? Installations like this would never work in CA. Can’t have all that stuff on top of the dash. No matter how it’s installed. Aren’t you worried about heat damage during the summer? What about all that stuff just being visible to anyone walking by? You’re not worried about theft? Personally, I prefer nice, clean installs and this looks anything but that. Too many visible wires and cables for my tastes. I tried Velcro when I had a TM-741 to attach the control head to my center console cover. But our summer heat kept causing the adhesive on the back of the Velcro strip to come loose. I got tired the head falling off all the time during the summer heat.

Seriously, though, if it works for you, then more power to you! You’re not married, are you? I can’t see any wife putting up with all of this. Where would she sit? Or, maybe that’s your plan! It’s all good. We’re just having fun with you.

I think the joke is the pamphlet to the drivers right! Look close “National Interoperability Guide.”

Don lives in Indiana - checking his call is easy. He runs several amateur repeaters and appears to be very involved in emergency communications. While his setup may not function well in California sunshine, it probably works well in Indiana. The publication referenced as a "joke" can be purchased from the government printing office: This version can also be downloaded: It contains a fair amount of good radio information - no joke. Nice setup, Don. Mark Johnson
