The Midland is defiantly better than the Nagoya.. One person in our 4 camper caravan had the Nagoya and he was always the first guy out and he didn't have a backup so he was always the lost ranger..
They are pretty impressive but they will peter out pretty fast on the long haul or when around hills and trees. On a trip up the calif/oregon cost last summer i had to switch over to my Midland whip to get some traction talking with friends along the redwoods.. Overall, the stuby does very well.
DX has them in stock https://www.dxengineering.com/parts/cma-ca-712efc and GigaParts https://www.gigaparts.com/comet-ca-712efc-460-470mhz-base-repeater-antenna.html
i wasn't aware he got attacked.. You are right, that in itself will cause some major headaches, especially for a one man show.. I hope he gets threw the mess.. Sending a prayer.
they work well when driving in nearby groups but peter out on long range and or if your are within a lot of trees. I was given a MXT25 and for the most part i like it, it works well.
you haven't explained anything in regards to the difference in placing ground to battery or chassis. Nada.. Tu-Tu. But i bet if you google its you'll find Motorola recommends grounding to chassis to save on material cost since they offen install the transceiver brick the trunks or backends of vehicles..
you do what you want,, But i'll tell you, your reason is 100% incorrect. Like i say, until you can prove to me from an engineering stand point grounding to a separate location is beneficial over grounding at the battery location your point is mute.. And dont confuse from connecting sources with power vs sources that draw power.. Completely different scenarios!!
There is a huge difference connecting a battery charger to a battery and connecting a source that draws power.. The latter will have no effects on the vehicles electrical system or its can buss system regardless where you place its ground.. It's always best to place grounds at the common location with other vehicle grounds.
There is no proven reason to ground separate to the vehicle chassis vs. the battery ground. In fact, there are more reasons not to ground to chassis then to the battery ground. Especially in vehicles built today having various chassis insulators, protective sheet metal coatings and metals with poor conductivity. If you can provide an reasonably explanation from an engineering standpoint, you might have my ear..
Try installing a braided ground strap from your hood to the opposite chassis and even across your exhaust and the chassis. Use an inline noise filter, Kenwood and Icom make a nifty one and use ferret beads.. Make power connections directly to the battery with quality 10GA wire. both ground and positive. That should eliminate most all your noise problems. Ram Trucks are notorious for generating noise in Ham radios... I've applied everything i mentioned to friends with Rams and problems eliminated.
certainly a lot of questions on voter integrity.. Last i checked, AZ leads with the most arrest for voter fraud and holds title for the most allegtions against fair elections.. Yup, getting ready to leave Calif myself, and AZ was the last place to consider..
