00:00If you've ever hauled your QRP rig out to a park or a summit and realized your antenna won't
00:04actually connect to anything, you know that sinking feeling. The little M10 to SO239 adapter
00:10base is one of those parts nobody thinks about until it's the only thing standing between you
00:14and a contact. So I went digging through the listings, compared the ratings, the sales numbers,
00:20the prices, and pulled together the 5 best HF antenna adapters for QRP radios you can grab
00:25right now. Let's get into it. Starting off with the SuperSail M10 thread with SO239 base adapter,
00:33built for USDX QRP radios and the PAC-12HF antenna. This one's the crowd favorite by volume,
00:39nearly 5,000 units sold and sitting at a solid 4.8 rating, which tells you people are actually
00:44using these in the field and coming back happy. The machining on the SO239 side is what stands out,
00:50the threads bite cleanly and you're not fighting a wobbly connection halfway through a QSO.
00:55It's the priciest of the bunch at $131.24, so it's not the budget pick, but if you want the
01:02option
01:02with the longest track record and the most buyers backing it, this is the safe bet.
01:07Next up is the USDX QRP radio PAC-12HF antenna M10 thread with SO239 base adapter,
01:13and honestly this is the one I'd hand to a friend just getting started.
01:17It's got a 4.9 rating across more than 4,500 sales, which is a genuinely great score,
01:22and it's the cheapest on the entire list at $83.23. Same M10 thread, same SO239 base,
01:30same compatibility with your USDX and PAC-12 setup, you're just paying less for it.
01:35If you're building out a portable kit and want to spend your money on the antenna rather than the
01:39adapter, this is the smart call. Best value on the list, no contest.
01:45Third is the shortwave antenna base kit with the M10 thread and telescopic antenna base.
01:51This one's a little different because it's the only true kit here, and it's rated for 13.5 to 55
01:56MHz so you've got real usable bandwidth for shortwave listening and ham work alike.
02:01It's carrying a perfect 5.0 rating over more than 4,000 sales, which is rare and worth paying
02:07attention to. At $116.57 it sits in the middle of the pack price-wise, but you're getting the
02:14telescopic base included rather than just the adapter on its own. If you want one purchase that
02:20gets you closer to a working setup, start here. Coming in fourth, the single-pack antenna mount
02:26with M10 thread and so 239 base adapter for USDX QRP in PAC-12. Another perfect 5.0 rating,
02:34over 4,000 sold, and priced at $91.66. What I like about this one is that it's just clean
02:41and
02:41simple, no extras, no gimmicks, just a well-made mount that does its one job properly. The build
02:47feels solid in the hand, and buyers consistently mention it doesn't loosen up under the weight of
02:51a longer whip. If you already own your antenna and you just need a reliable
02:56base to bolt it to, this is a very easy yes at under $100. And rounding out the list,
03:02the red anodized version of that same antenna mount M10 thread, so 239 base, USDX and PAC-12
03:07compatible, at $93.74. Yes, it's about $2 more than the standard one, and yes, that's basically
03:16for the color. But hear me out, when you're packing up in low light after a portable session,
03:21a bright red mount is genuinely harder to leave behind in the grass. It's got a 4.9 rating over
03:274,000 sales, so the quality is right there with the others. Small detail, but if you operate outdoors
03:33a lot, it earns its keep. All five links are down in the description, so go grab whichever one fits
03:39your setup.
