Antenna mount for 2025 Jeep Gladiator Mojave?
marcspaz replied to WRTC928's topic in General Discussion
Just remember the corner caps are plastic. You should have the mount forward on the hood about 6 or 7 inches for a good ground plane. -

Question re: grounding for lightning protection
SteveShannon replied to WRTC928's question in Technical Discussion
The rule of thumb is that the distance between ground rods should be twice the length of the ground rod. Anything less results in minimal additional protection. The wire is used for bonding, equalizing the potentials of the different ground rods, not carrying the full current of a surge. The nearby ground system takes the brunt of the current surge. A water jet might be able to do it, but maybe cutting the asphalt is easiest. -

Question re: grounding for lightning protection
WRTC928 replied to WRTC928's question in Technical Discussion
Okay. For some reason, I was thinking 8'. That's still a lot of ground rods for a 200' run. The code is a minimum. My thought was that for such a long run, a heavier wire might be preferable. If so, I'm okay with absorbing the extra cost. I can't think of any way to go under 30' of asphalt without cutting it. -

Exactly. Best is to disconnect it before it enters the house. -
Question re: grounding for lightning protection
SteveShannon replied to WRTC928's question in Technical Discussion
If you use 8’ ground rods they should be driven every 16’. There’s no benefit from placing them every 8 feet. Code doesn’t require 4 gauge. It requires 8 awg. I wouldn’t cut the asphalt, but I would go under it. Burying the ground wire is fine, even preferable.

Question re: grounding for lightning protection
WRTC928 replied to WRTC928's question in Technical Discussion
My question really is whether it's safer to leave the antenna connected to the radio or to disconnect it. I assume a direct strike may fry the coax even if it's properly grounded. I can replace an antenna and coax; it's my house and myself I'm concerned about. -
Question re: grounding for lightning protection
WRTC928 replied to WRTC928's question in Technical Discussion
200' of 4 awg copper wire is about $300 which isn't prohibitive, but if you have to add another ground rod every 8', that's going to get into some serious cash, aside from the work of driving 25 ground rods. In my case, I have to cross about 30' of asphalt. Is there any reason I can't cut a groove in the asphalt, lay the bare wire in it, and fill it with asphalt patch material? Is there any disadvantage to burying the wire where it crosses grass? -
Question re: grounding for lightning protection
SteveShannon replied to WRTC928's question in Technical Discussion
Less risk, but not no risk. The coax might still be at risk. What’s the breakdown voltage for the insulation of the coax? A long piece of coax exposed to a high voltage pulse at one end but disconnected at the other end can still be damaged. And what about the center conductor? It isn’t grounded unless you have done something to ground it. Depending on the design the antenna radiator elements are not usually connected to ground. - Today

Question re: grounding for lightning protection
WRTC928 replied to WRTC928's question in Technical Discussion
So, what happens if the antenna is adequately grounded and you disconnect it from the radio? I have assumed the electricity would follow the path of least resistance to the ground and the coax would be at minimal risk. Is that incorrect? -
I got myself an H3 Plus to add to my stable of H3s and my Wouxun KG-935G Plus. Looks like a nice unit but I'm having trouble upgrading to the newest FW. I get a "Initializing device zone: app_dir_head" message on the Odmaster web GUI, and the upgrade never gets past that spot. I'm using the official Tidradio cable, I've tried all of the available USB com ports on my laptop, and even tried using the manual upgrade tool Tidradio provided via their FB group. Anyone know of a solution?

Antenna mount for 2025 Jeep Gladiator Mojave?
WRTC928 replied to WRTC928's topic in General Discussion
The hood is aluminum IIRC. Hopefully that will be adequate if we mount it on a fender or hood lip mount. A lot of people seem to get good results that way. Since I already have the SG7900, it will cost nothing to find out. -

By "two lined version" are y'all both referring to plain UV-5G? Holding down "8" while turning on does nothing on my plain UV-5G. Holding 3 still works though to give the firmware number (and it isn't what Chirp shows).

Welcome! Feel free to ask whatever questions you might have. That’s how everyone starts. We don’t do much one on one consulting because whatever questions you have, someone else is likely to have, or perhaps has been asked before and we can point you towards the answer.

Question re: grounding for lightning protection
SteveShannon replied to WRTC928's question in Technical Discussion
That won’t protect the radio at all. Electrons don’t stop instantly and between the antenna connector and the power input there’s a lot of components that are at a different potential than the coax shield and center conductor. Yes, it’s not cheap. Tying all of the legs to a single ground rod requires changing the path of the discharge. Having a ground for each provides a straight path to ground, plus having more rods reduces the impedance going to the ground. In an engineered ground system such as a substation you might even see a ground mat, chemicals, and other things done to minimize the resistance and create a large bed of equal potential. -
I’ve reported this to Rich.

Question re: grounding for lightning protection
AdmiralCochrane replied to WRTC928's question in Technical Discussion
It was all about EMF and loops that absorbed it. Any luck involved was whether the loop was tuned/angled to the wave that passed thru it. -
Question re: grounding for lightning protection
WRKC935 replied to WRTC928's question in Technical Discussion
Yes, there is always going to be a difference. You bond because coax connectors are NOT high current rated. The circular mills of the shield conductor is also not sufficient to minimize the resistance of the conductor. This is why you don't use split bolts and crap to do your grounding. It's all CadWeld or 15 ton compression lugs / connections. -

LeoG replied to WRTC928's question in Technical Discussion
Lighting is just like tornadoes. Destroying one while barely touching the one next door. Could have been grounding, or just dumb luck. People struck by lighting can survive or become crispy kritter piles of dust.
