What have you? I'm primarily interested in a tilt over / guyed but will consider freestanding AS long as they can be engineered to 110MPH wind spec. Primary suspects include Rohn 25 and 45. 73 de Nor
Hi all! I'm helping a friend set up a 40 m dipole on his tower. It hangs at approximately 30ft. The dipole is in a flat top configuration. There is some droop on the ends, but not too much. We have t
Up that is! Hi All! I've got a 20' stick of Rohn 25 with a Yaesu 5600b (split with the az in the tower on a Rohn plate and the el up on a mast) rotating a pair of M2 antennas. Installed with the ante
The problem is that they are switched manually. I've got a pair of DPDT relays NC thru and pulled preamp engaged, for VHF and another pair for UHF. Wish I could do it your way. Need some sort of weat
Purchased a M2 436CP30. Had a failure of the switching block in less than 5 years. White plastic cracked and allowed water to ingress to the switcher. Customer service?? No return call. Pics on reque
You've got to be kidding me. See here: http://www.flickr.com/photos/n3ykf/11312549334/ for pics of this junk. Been out five years. They cost $500. Hardly worth it. Bad manufacturing practices or engi
Wish that were the case. I've spoken to the "team" at M2 twice. Actually was told to "F@@K off." Requested to speak to Mike twice. Those people are a bunch of idiots. I won't hold my breath for a cal
My story fishy? M2 sells the ANTENNA with no switching hardware for $291. Add the circularity sw and shipping and you just hit $500. Might get away with a Tohtsu relay but without custom made phasing
Hi all! Wondering if such a beast is possible. Have looked at the Rohn FK series of towers. However, the max wind speed that the tower/antenna load is rated for is 90 MPH. I have a feeling that I nee
Hi all! I have a preamp that I switch in and out with a pair of spdt coaxial relays. The NC positions pass through and the NO positions hold the preamp. The relays are +24Vdc and the preamp needs ide
I have double shielded 18Ga 4 twisted pair wire. When I terminate the wire, what do I do with the braid shield. There will be 40W UHF or 50W VHF max around, so the idea of protecting my sensor's (5V
The rotator is complely homebrew. Cables carry various DC signals. One cable carries 2 motor poles (4 wires), the other carries a 3 wire sensor set with ground and +5Vdc (total 5 wires) _____________

Hi all! Looking for four of the said connectors. Thanks, Norm n3ykf _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@co
We have a fully stocked Rohn dealer (Three Star) down here in central FL. Isn't there one within a reasonable driving distance? I have a Hyundai Accent. Picked up an entire kitchen/bathroom cabinet o
Hi all, Am getting ready to work with a pair of engineers and spec out a 12 KW installation. There will be 3 poles with 14 modules on each pole. The inverters will be at a central location in the pan
Hi Roger! Good to hear you again. All you say is true with HF antennas. On the other hand, what about VHF and higher? Looking around I've found a bunch of stuff on optimizing and qualifying antennas
Check out k3ng's arduino based controller. Has a NMEA interface with sun/moon tracking. It works fairly well. _______________________________________________ _________________________________________
Hi all! Looking for Rohn (or equivalent) guy anchors (ex. GAR30). Pickup preferred. Am in central FL. Thanks, Norm n3ykf _______________________________________________ ______________________________
The reason that I've had to ask the list is that my go to store does not hold stock here in Orlando any more, it's just an office. Called this morning and wanted to make sure that they had the items.
