The Other Half of Your Antenna Has to Go Somewhere
von Jon KL2A

A wire up the flagpole, a 49:1 at the base, and an SWR meter reading 1:1 -- so why is nobody coming back? Because half of that antenna is missing, and the yard was never going to hold it. The physics, the fix, and one question to ask before you spend a dollar.

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!

Game Changer

It’s not the weight of the antenna - it’s the fulcrum. Before the tilt up base it was a two person job. Now it’s a very simple operation to raise and lower the antenna. Great addition, especially in Eastern North Carolina where severe weather is abundant.

An old ham and the tilt-up base

I purchased the tilt-up base to make it easier to maintain the flagpole. I am 77 years old and I have no trouble raising and lowering the antenna by myself. My wife assists me with removing and inserting the bolt while I steady the antenna. While I had the flagpole down I put lock washers and thread locker on all of the screws. We have enough wind here that over time some of the screws would loosen- hopefully this will solve that problem. My antenna is the DXF-24 flagpole. I also added the 9' whip.

Great Improvement!

Living in Florida, prepping for high winds and hurricanes isn't uncommon. Now that I have the tilt-up base installed for my DXF-24 flagpole, that preparation just got so much easier. Remove one bolt, loosen the other, and the antenna comes down easily and goes back up just as easy. It's now a one person job. Besides storm prep, it makes any preventative maintenance less of a chore.

Like the Greyline antenna hardware, the tilt-up base is beautiful. Added bonus; the flagpole just got a little taller! 73, N3EQF

Thomas — you described that base better than our own product page does. 'One person job' is exactly the design goal, and hearing it from Florida during hurricane season means more than any spec we could publish. Thanks. 73, Jon KL2A

Flag pole

I enjoy having my 24 foot flag pole antenna. It looks great and with the pivot bottom it will be easy to repair or maintain if needed. Great job.

Thank you, Don. The 24 is the height where the low bands start paying you back — try 20-30-40 after as darkness approaches. Have fun. 73, Jon KL2A
