Heavy-Duty · 3-Inch OD · One-Person Raise and Lower

The 3" HD Tilt-Up Base — Walk the Heavy One Down.

Built for the 28' HD and any straight 3-inch OD pole. The same idea as our standard Tilt-Up Base, scaled for a heavier antenna: a one-direction pivot that stops dead at vertical, so one person lowers the whole antenna to waist height for maintenance, a whip change, or ahead of a storm — and raises it back the same way.

Ships in 1-2 Weeks

Built alongside the 28' HD and shipped in the same window. Order them together and they go out together.

Watch: 14 Seconds

One person raises a 24' Greyline alone on the standard Tilt-Up Base. The HD tilt uses the same pivot, scaled for the heavier pole. Watch the 14-second raise →

Fits

Great addition to My 20V!

After 2 weeks of use I can safely say that the 9' whip is a great addition to my 20V! My rough calculations show about a 2+ db improvement overall. On the receive side the most dramatic indicator is that I am getting approximately the same signal strength without the preamp on most bands. I am also getting more reports in the + range on FT8 than previously. I have used PSK reporter to get a general picture of my RF footprint and signal strength compared to to the original 20v w/ previous reports. I have also been able to work several new countries that I could not work previously...India, Franz Joseph Land, Kahazakistan. India is certainly not rare but it has taken me three years to eliminate my "blind spot". Swr is well below 1.3/1 on all bands 80m-6m using the LDG RT-100 at the antenna. All in all could not be more pleased with the 9" whip addition!

Franz Josef Land and Kazakhstan on nine more feet — that's the report every whip page wishes it had. Thank you, Craig. Your words are on the page now. 73, Jon KL2A

Worth every penny!

I added this tilt mount on my older (2.25") 28' flagpole and I couldn't be more pleased with how well it works for me. I can now drop down or raise my flagpole by myself in about 5 minutes in each direction. This mount is an engineering beast with how well it is constructed! Previously I had to wait and get another person to help lift the base out of the PVC pipe and help lower it hoping that it came down as planned. Going up was even more of a challenge getting the base into the hole and raising it back up. That's 33 feet of wiggling aluminum and not so easy to manage even with two people. With this mount I don't even give it a second thought about doing maintenance or lowering it for an impending storm. It's straight coming down and going back up with no overshoot. Or worries. This is an excellent investment in both time and money!

An engineering beast' is going on the shop wall. 33 feet of aluminum, one person, no overshoot — that's exactly what we built it to do. 73, Jon KL2A

Aperture makes a difference

I find that the added 4 feet makes a difference, along with the 9' whip and tilt base. Signals are stronger on receive, and my transmit reach appears to have extended based on signal reports. Still adding many DX contacts to the log! Looking forward to getting the aluminum cap for the 2" to whip transition. I believe that will help as well.

Christopher, the extension, the whip, and the tilt together are the full aperture system, and your log shows it. Thanks for taking the time to write this up. — Jon KL2A

Size Does Matter!

I was already happy with my DXF24 flagpole, but adding the 4' extension made a great thing even better! My setup is the 28' flagpole with the tilt-over base, 1:1 balun at the base with 40' LMR400 to my KAT500 tuner in the shack.

My first week after adding the 4 foot extension (a super easy job with the tilt-over!), I logged RI1FJL on 15m and P29YY on 17m, and discovered I could now make QSOs on 80 meters. I hadn't made a QSO on 80 meters I moved into this HOA community 21 years ago!

If I had room for the 9' whip on top, I would add that next and probably gain 160 meters. But this current flagpole setup is giving me 80 thru 6 and tons of QSOs, all with convenient band switching from my shack. Yes, it's fun again!

Tom, 80 meters for the first time in 21 years, from an HOA lot — that's the whole case for aperture in one line. RI1FJL and P29YY in the first week didn't hurt either. Thanks for the report, and see you on 80. — Jon KL2A

Doesn't get any easier

I've had my 24ft flag pole for about a year and each time I wanted to do any maintenance it required another person and even then as we get older it's a task and a half. The installation of the tilt up base was to easy. As described by others, loosen the three bolts, remove the second one and up or down is a cake walk. I always had a little wobble at the ground when the wind blows so I fashioned a shim from some aluminum flashing, shaped like a shoe horn and now it remains straight up in the wind. I have some experiments planed which I will now be able to do without help from another person.

Bart, no second person, no ladder, maintenance on your own schedule — that's exactly why the tilt exists. Thanks for the shim tip too; it's gone to our shop. Enjoy the experiments. — Jon KL2A
