The victim. An ‘04 Triple Nickle CTD (Cummins TurboDiesel) with the mans’ trans. Nearing a quarter-million. Stock, but for road performance anti-roll bar changes (after a Peterbilt, it’s my diesel Corvette) with a bit more to come along that line to further enhance towing. A 1T, but with IFS plus rack & pinion. 2WD, 8’ bed. Started life as a business vehicle, now it’s my garage for what I don’t want in the Silver Streak (background). As 24-MPG Highway is my Solo planning number, and 15-MPG Towing, it’s a great vehicle. I’ve had a few sits-on-the-center-console Radio setups as where to mount is sure different than 1974. Giant antenna mag mounts, hood lip mounts, etc, have been used, but as I’m going to keep the LEER-brand composite topper, a bed mount antenna is out. I’ve worked my way thru the Undertaker museum certification course on mobile AM antennas, so that end is covered except one. 1). The selection is of 5’ plus antennas extends to 102”. But I’d also like to run a Larsen NMO-27. — I know there are adaptors both directions. But, quality? (Opek doesn’t give me tingles). — So, before I get to roof cutting next week with a Greenlee Chassis Punch ordered, I also need to order from BREEDLOVE MACHINE a 3/8-24 mount. Or? — Any thoughts generally, and any on being able to swap in an NMO Mount Larsen — with an adaptor— on occasion? — I’m not averse to more than one hole (the Larsen isn’t any priority) so a separate NMO Mount is fine. A future job. Radios will be the modern Uniden digital series (880, 885, 980), President McKinley or Lincoln. Plus a grab bag of Galaxy (979, 99v2, maybe a 95T). The truck is an AM/SSB platform till further notice. From 4W to dual finals to outboard amp. Whatever I get in the future (for big truck, travel trailer or pickup) gets installed and tested here. Any type or description (a Yaesu t450d is waiting it’s turn). There’s no true “base station” for me, as it were. My gear will always be “mobile” in a sense (even if someday it’s not considered mobile or portable). So until some receiver or transceiver for which I’ve earned licensure to TX/RX, the pickup MAY be part of testing. Even if driven away from trailer to get reports. So, first hole & first mount . . . How would you proceed? (Thx for your consideration). .
