I like my LM-470D and have found Tashjian to be easy to work with. I suggest you go with the motorized up/down as hand cranking gets old real quick. Also, make sure that the motorized up/down has pos
The CD-45II uses a friction brake to keep the antenna from turning when the rotator is not activated. If you have any wind at all the brake will not hold. I suggest the Ham-IV as it has a wedge brake
I purchased a pair of 6' long nylon straps with loops on each end at Copper State Bolt in Phoenix, AZ. They work great. de Paul, W8AEF _______________________________________________ See: http://www.
When I was cutting stubs for a DXpedition I concluded that the length included all wiring after the loading capacitor in my amplifier to the end of the stub. They worked great on two DXpeditions but
You may want to invest in an antenna modeling program and observe the effect of different heights on your yagi. I did this last year and for a 2el 80m yagi I found that .6 wavelength yielded the patt

I have a prop-pitch rotator that will turn just about anything. $200 you ship (it's heavy) from Phoenix, AZ. de Paul, W8AEF _______________________________________________ See: http://www.mscomputer.
I used to wear heavy boots with a steel instep and had the same problem from climbing my HDBX 64 (extended to 88 feet). One trip up the tower I observed my feet were not hurting - I had my tennis sho
I'm glad someone beside myself noticed that article. The LCR meter is worth several years subscriptions to me. de Paul, W8AEF _______________________________________________ See: http://www.mscompute
One of the magazines (73?) ran a life test on rotators many years ago. The test consisted of mounting the rotator horizontally, installing a 10' mast, and hanging a cement block from the far end of t
Not true my LM470. There are two pull UP cables on each side of the upper sections. Only one pull up cable for the 2nd section from the bottom. The upper cables are not redundant but are arranged suc
There are two pull UP cables, one on each side of the upper sections. Only one pull up cable for the 2nd section from the bottom. These are in addition to the pull down cable. What a difference a wor
My wife made the decision 45 years ago that she would rather know where I am (at the rig) than have me off, hunting, fishing, or just carousing. She not only tolerates my towers and antennas, she enc

Take a look at the raising fixtures that are sold with crankup towers. They all pull below or at the center of the tower. de Paul, W8AEF _______________________________________________ See: http://ww

I have not had any problem with the belt on my '470 slipping, but then we don't have cold WX in Arizona <grin>. It could be the clutch on the driven pulley that is slipping, and that is adjustable. J
The hub of the driven pulley is a clutch. This is true on my LM-470 and was true on my HZN-354. (Not true on my Tristao TX-455). What I call the driven pulley hub is mounted on the keyed worm gear th
It could also be that the belt is too narrow and rides in the bottom of the pulleys. The belt dressing is a good idea. Even if it slips when first applied it will (should) reduce slippage in the futu
