    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation.

The faceplate has 2 round magnets that attach it to the bracket. That way you can remove it easily and use it. But the magnets are strong enough that the display stays put firmly and doesn't wobble when you push buttons.

Very nicely done! The thought of drilling a hole for the antenna in a new vehicle makes most people tremble, but most don't think twice about drilling holes in the console or dash to mount a radio.

How is the transmit and receive with the new setup?

It's a sweet install, and thanks for the pics.

The SWR on VHF is absolutely flat, but UHF is around 1.4 - 1.6. So I kinda wish UHF was a little better. I think until I've had a little more time to drive around, I won't be sure how great the performance is. So far, I'm able to key up repeaters a county away on 15 watts next to my 3-story apartment building, so I guess that pretty good!

If you do lots of ragchewn' on high power, you may want to think about replacing the. Element with an open coil, they have a history of melting under high power when not moving, seen a couple around here bent at odd angles. Looks good, Nice job

I don't do a lot of rag chewing, and the plan is to pretty much keep it on medium power (15 watts). The antenna is rated for 200 watts, but I guess it can still melt? Is it even safe to transmit 50 watts from an antenna that is only about 5 feet from the back of my head?

I used to have a closed coil version, lost it in one of my many moves, and although I never had issues, I have seen them melt the loading coil by long winded old farts. Chances it was more than just being on high power ( road salt intrusion ect). I would not put more than 50 watts into it.

There was a guy near where I live, that was using a 75w mobile, rag chewing, in the summer, not moving and his closed coil melted down.

I love Larsen antennas, I currently have an NMO 2/70 with the black open coil element. I like the antenna, it works VERY well, in fact I would not trade it for any other dual band antenna on the market. I have mine in the centre of the roof of my company truck, hole mounted. There is a UHF repeater that is in a really good location, that I can use any where with in 80-90KM of it. VHF is pretty decent for only being a half wave with no real gain to speak of as well.

Honestly, I do not have the math skills to figure out what kind of energy one would be exposed to, but I have a 45w commercial radio that the antenna is venter mounted on the driver side of the same truck. Chances are that there is not a great risk with the antenna on the trunk @ 50w.

Say that again?
I think what the poster is saying is the "teeth" of the NMO mount that grab the underside of the trunklid aren't aligned front-to-back. When a vehicle is in motion, the wind resistance on the whip wants to pull the antenna back and by having the mount teeth aligned front-to-back it counteracts that pulling force.

Nice clean install regardless. Where did you mount the speaker?

The speaker is mounted on the console. You can see it in the forth photo above, behind the mic cord. That's interesting about the NMO teeth. I slowly read up on this and watched videos for several weeks before doing the install, and that's one issue I didn't see.
