Might check around with local horse folks. A horse trailer is typically two stalls, floor close to ground, and a nice tilt-out shallow-angle loading ramp. Relatively easy to load a tower, pieces of p

We have been measuring wind here continuously for 40 years -- currently, for last 2 years, have a 900mhz Davis Vantage Vue Model #6351 wireless mounted up 25' on a 2-foot arm facing into the directio
For completeness in the Phillystran discussion, the "Lok-Cube" should perhaps be mentioned. These were provided with 1990-vintage KT34XA antennas to terminate the 1/8" Philly boom truss.. This item i
Even with the potential hassles mentioned, when cell tower folks come around lusting for your tower, it is still a Golden Opportunity. We tested their level of desperation. When the Cell Guys knocked
The W8JGU Sidemount is reviewed by Randy K5ZD in a late 1980's issue of NCJ. Very simple. It uses *No* precision ball or roller bearings. The radial loads are taken by a rotating pipe inside a slight
We erected 80' of Rohn 25 solo. First section was in the concrete base. We used a hand-cranked boat winch, 1/8" steel cable, which attached to the tower side tubes, with two u-bolts, anywhere desired
Might exercise caution on what chemicals are getting dumped into the ground. Check fed, state, local regs.if uncertain. e.g., some fly ash contains arsenic. Would not want to inadvertently turn your

The true beauty of this water-drilled excavation method is it can be done to a large extent without damaging any underground services or structure. You could see in the video what appeared to be unaf
hydro excavation http://hydroexcavation.com/information/ works in most soils, even the hard-packed clay in our area that you can't shovel without first picking to break it up. Don N7EF ______________
The editors were likely too distracted by the Cover_Babe to pay much attention to the finer points of tower-climbing equipment. Think of it as something akin to a QST Swimsuit Issue.... Don N7EF ____
Now, if you had a solar-powered GPS sensor mounted on each end of the boom, wirelessly transmitting those two positions to a receiving unit in your shack, the azimuth of the boom could be computed an
We mounted a 30-meter full size dipole at 76' assembled from 204BA parts on the side of a Rohn25 tower with coaxial balun. It is spaced about a foot away from the nearest tower side rail, with a matc
Actually, the *tower* you have this on can make a difference. Our 80 ft of Rohn25 makes a pretty slick torsion bar for absorbing rotational shocks that might otherwise cause slip at the clamp (or dam
