The operator with a tilt base walks the pole down on a calm afternoon, works at chest height, adds lock washers and thread locker, and walks it back up. That is the difference between maintenance and repair. \u003ca href=\"\/ru\/blogs\/the-signal-report\/w7mne-kept-his-flag-light\" style=\"color:#B8960C;font-weight:bold;text-decoration:none;\"\u003eRead Denney's full story →\u003c\/a\u003e\u003c\/p\u003e\n\n    \u003cdiv style=\"margin:0 0 24px 0;\"\u003e\n        \u003cp style=\"font-family:'Courier New',Courier,monospace;font-size:11px;letter-spacing:2.5px;text-transform:uppercase;color:#B8960C;font-weight:bold;margin:0 0 8px 0;\"\u003eFrom the Reviews\u003c\/p\u003e\n        \u003cp style=\"color:#555;font-size:15px;margin:0 0 12px 0;\"\u003eOwners keep landing on the same idea in different words.

It was always scary lowering and raising a 28-foot flagpole, worrying about which direction it might want to go if it got away from me. This base is something I've been wanting for years, and now it's available. Loosen the top bolt and the bottom two bolts, remove the second bolt from the top and it walks down easily. A five-minute job. Going back up is just as easy and quick. The best part is it stops at vertical. No more worrying about bringing it down or up. This is an awesome investment for my antenna and personal peace of mind. It's well worth every dollar.\"\u003c\/p\u003e\n\u003cp style=\"margin:0 0 10px;font-size:15px;line-height:1.65;color:#e8e8e8;font-style:italic;\"\u003e\"I also replaced my RG8X coax with LMR-400 thanks to Jon's coax information.
