Some have read the other post that I sort of hijacked with my crazy GMRS plans. Guessing some have questioned the validity, my ability, and said " cool story bro". Here is what we started with in the winter of 17. https://flic.kr/p/2hLHs8V To say it was a mess is an understatement. The previous owner had contracted crack heads to do the tear out. They took anything metal. They even took a door. Not to mention every bit of conduit. I had been in the site 6 months prior and everything that AT&T had there was still in the building. It took 3 very large roll off dumpsters to get it all out of there. So I went to work rewiring, reworking and rehabbing the building. At this point, we have a large AREDN (Amateur Radio Emergency Data Network) with access nodes on all four corners of the tower covering 900 2.4 and 5.8 There is a large ham packet switch network hub in place covering all bands including HF. And of course a GMRS repeater (soon to be more). Not to mention the ongoing projects. A Centracom Gold Elite console system. Several ham repeaters, DMR and analog. I semi serious HF station... More antenna's to be installed in the spring. Couple shots of the interior https://flic.kr/p/2khe2Ti https://flic.kr/p/2kjeWTE Now there was some discussion about my plans to put up 4 GMRS repeaters and how that was going to happen. Here is the 8 port combiner https://flic.kr/p/2kjeofT https://flic.kr/p/2kjaCPs Some of the repeaters https://flic.kr/p/2kjeWGT https://flic.kr/p/2kjeo64 The MTR on top is the current GMRS repeater we have on line. The XPR's in other photos are going to be used as well for this endeavor. Here is the Centracom CEB stack. This is a work in progress that will be interfacing to the control stations in the second photo and the repeaters as I get that fully programmed and running. https://flic.kr/p/2kjaCA1 https://flic.kr/p/2kjeo88 Up till now, it's all just in a block building. So here is the tower next to the block building https://flic.kr/p/2hLJtx7 And a couple photos of the firefighters training on the tower. We donate access for high angle and rope rescue to all fire departments in the area. https://flic.kr/p/2khdz69 https://www.flickr.com/gp/36646490@N05/hzD6f1 So that's what I am working with. It's been time consuming, but fun. And the best part is, since it's all private, I can do as much or as little as I feel like on any given day. Specifics on the tower. Height 239 feet to the lightning rod tip. 43 feet from leg to leg. Two decks on top, one is octagon. The lower is square. THe lower deck is 40 by 40 with 4 horns Upper deck we haven't measured, but it's smaller, has 2 horns. Since I always get ask about the horns. They are 12 foot wide and 15 feet tall at the apex of the top. Electrically they are a section of a 24 foot dish. Beam width is 1.5 degrees and the mathematical gain is just under 40 DB for 11 Ghz and 30 something for 6 Ghz. Feel free to ask questions.
