Ha. I don't drive a Volvo by choice, either, lol. I intend a vertical dipole antenna setup, similar to what the OP has done, just on the back. That way, the grounding isn't an issue. I've never been able to achieve decent grounding, anyway; which is why I tried the dipole setup, to begin...

I was actually thinking of mounting my 102's from the grab bars on the back ferrings of my Volvo, and letting the antennas stick up about a foot over the top of the whole rig. If I flip the grab bars over, they should stick out from the sides of the truck. It's just the coax that's going to...

2 minutes in, and I have no clue what he's rambling on about. Not much interested in the remaining 106 minutes.

@dieseldriver ; I see that you've got a similar antenna setup to mine. Does that bottom antenna have a tendency to beat against the side of the truck in high winds? My antennas are currently mounted on the top bar of my Volvo mirror bracket, with the bottom antenna lashed to the bottom bar of...

I didn't realize DOT was in the business of measuring antenna height. I did have my antenna mounted, at one point, so that it stuck up about a foot over trailer height. I ended up moving it, because the location still blocked too much signal. I guess I'll refrain from mounting my 102" whip...

Are there antenna height regulations for a mobile CB unit? I haven't been able to find any; and I have done some looking. I have found height limits for base stations (60 feet, or 20 feet if on a roof top), but nothing for a vehicle.

Another reason for angled antennas, is so that the wind will push the antennas back to straight, when the truck is moving, as opposed to the wind pushing the antennas into a backwards angle. But, as is often the case with useful modification, folks pick up on it without understanding it, and...

Real analog gauges? That's amazing. I don't think my 80's era Chevy van even has analog gauges. Though, I could be wrong. Never had to check.

Spiffy. I wonder if they'll do a 985SSB? That would be kind of fun.

Us truckers; we do funny things. I often see old cab overs with dual antennas, mounted on the front top corners of the cab, at an angle nearly parallel to the ground, like the truck is a snorting bull, ready to charge. Either that, or their at about 45 degrees. Then they look like bugs, with...

I also have an '03 Avalanche. It's plagued with a host of minor electrical gremlins. I haven't even put a radio in it, yet. The problem with modern vehicles, is that they don't really have gauges anymore. They, at best, have digital readouts that are presented in a simulated analog display...

I'm no engineer, either, lol. I'm also not educated enough to understand the reasoning behind either the 492/F formula, or the 468/F formula. I'm still pretty new to this stuff. I'm pretty sure that I have an explanation of it in my antenna book; I just probably haven't gotten that far into...

That's a right spiffy little calculator. According to that, a 1/4 wave at 27.185Mhz (channel 19) comes out to 108.5 inches.

I got my 980 for free, essentially. Redeemed some Pilot/Flying J points for it, while it was on sale. I got a SiriusXM receiver, at the same time, also on sale. And that had a nice rebate with it, too. I basically got paid to take a couple of big ticket items, lol. No, the 980 isn't a big, bad...

I divided 11 meters by 4, which gave me 2.75 meters. I then went to Google, and had Google convert 2.75 meters into a measurement in inches. The result was 108.2677 inches. I suppose that, since I am most frequently on Channel 19, I could tailor the antenna to that specific frequency, but...

1969 was 48 years ago, not 38, lmao. That must be the first question ever asked of the interwebs.

1 quarter of 11 meters is 2.75 meters, which equals 108.2677 inches. So, the extra 6 inches is to stretch that 102" antenna out to 108", which makes it closer to an actual 1/4 wave.

Was he upgrading to something a little more heavy duty, I wonder? Or, is he just replacing them because he could do it swiftly, and charge a nice premium for it?

Early this morning, I went into a Bosselmans truck stop, in Nebraska, and found some 102" steel whips. I bought two of them. Oddly, they had no 6" springs to go with them. Nor did they have anything else with which to add six inches. That's ok, though. I'll find it, elsewhere.

I can't speak to the 90's era Road King mics, but Road King, now, is owned by DAS Companies, who also owns Astatic, Francis, Wilson, and K40 (and some other random companies). The primary function of DAS is to stock travel centers, such as Pilot, TA, Ambest, etc. Eventually, I will eliminate...
