No need to mount anything the wrong way up.... Many of the older TV rotors had the mast go right thru the rotor so no need to mount the rotor upside down... And even in the case of the bell type roto
It might be worthwhile to point out that this applies to 75 ohm hardline only, as the center conductor of the 50 ohm stuff is larger. On the 1/2" 50 ohm hardline I have, the center conductor will go
This is just plain old precipitation static - we experience that probably 50 times a year. Exactly as you describe. Tom covers the subject very well in his site: http://www.w8ji.com/pecipitation_stat
The Delhi tower here in Canada is similar (X braces farther apart so not quite as rigid) and while they aren't the greatest tower to climb, the best way is to climb on a corner so your feet have a re
I am familiar with the original HyGain version of that antenna, the 3-30 mhz version and the double tower and large rotating mast. First point - you DON'T need a 70 ton crane for this. A smaller cran
The VE6FI one is what I'm familiar with. Mine is similar - 4-30 mhz made by Sabre (more ex HyGain types). Plus a 6.5 - 40 Collins that just went up this fall. It's pretty unreasonable to try to clear
I monitor power (and many other things) remotely using the ~$90 Aviosys 9100A 4 port analogue video to ethernet server (no computer needed) and then hook up inexpensive ($13) analogue cameras focused
The portion of the Alfa Spid that rotates is just the pipe coupler with the bolts that pin to the mast. This is well inside all of the other parts of the rotor so it seems highly unlikely that the ro
The Yaesu GA-3000 (I've not seen one) is made for this purpose. You can make one adapted from a vehicle driveshaft component, often called a flex disc or a guibo. Also perhaps a LoveJoy or similar co

The Hygain T2X or Ham M style both are around 14.5" tall (without the lower adapter) The AlfaSpid standard RAK is around 15" and the smaller RAU is a bit under 14". The larger Spid RAK is around 14.5
A tired capacitor can be the culprit too.... _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lis
I wouldn't be concerned about stress on the rotor in this situation.. It has 2 levels of pretty sturdy bearings and can take lots of side force. I might be a bit more concerned about the capability o
If its a straight run and no bends 100' should go smoothly. Any rope will be fine, that cheap 3/8 poly trucker rope is plenty good enough. A few half hitches around the bundle and some tape to secure
Simple - make your own vertical "standard" with a plumb bob suspended from something (a step ladder perhaps) out maybe 50 or 100 feet away from the base and that will tell you which is vertical.... 7
That doesn't compute.... If you truly have 2" OD x .250 wall you need just slightly <1.5 " OD to fit inside not 1.750. The overlap isn't critical - a foot on either side is fine - but the wall thickn
The greatest bending moment is at the bottom of the gin pole where it attaches to the tower, not in the center. _______________________________________________ _______________________________________
He's measuring the resistance of the current limiting resistor (inside the rotor housing) which is in series with the reed switch. This is typical of a lightning strike event that welded the reed swi
