This is good advice. Since the elements are all full size, you will likely want to split the 20 and 15 elements so they can be easily carried on a 12 or 14 foot trailer (preferred), or your roof rack
I purchased a new G-800SDX in 1998 and it had the 7 pin plug. Three years ago it was blown out by a lightning strike. I ordered a new plug and rubber boot from Yaesu thinking the damage may have been
20 gauge wire should work okay up to 150 feet. To make sure, just wire it up and give it a try. My 8V has been used during the past 5 field days only, so I do not have experience with long term outdo
Since I climb all of my towers, I consider "cheap" an unworkable word, no mater how much testimonial is attached. Heck, I even suspect all new and used OEM tower parts as "unproven" until they have b
I have one of these, and the manual. Calibration is not normally required unless components have been replaced. The main calibration involves setting trimmer cap C39 so the time base is 10MHz. If you
This (bench vise and Crescent wrench) is the way I do it. Have the turnbuckle handy to put on the thimble and the Crescent wrench can then be reversed to close the thimble while still clamped into th
I have used Arrow aluminum rivets with success. Comparing these to the factory rivets one can readily see the difference is in the mandrel. The Arrow rivets have an open-ended mandrel while the Force
Ya'll have me wondering about my 40M tower plan. Last fall I took delivery of two M2 40M4LLDD Yagis. This antenna has 4 elements on a 42 foot boom, but a surprisingly sparse 13 square feet windload r
Frank, Are you saying the Orion has a basic design flaw that no amount of strengthening or improvement will correct? If so, please elaborate. Thanks. 73, Keith NM5G --Original Message-- From: towerta
Thanks for posting the flaws again. Looks like one of the recent improvements is removal of the dimples. Both surfaces (front and back) on the mast clamps are now ground off at the factory. Since the
I don't think the drive can be back-driven. It's just that you would need about 30,000 in-lbs of torque to break anything. 73, Keith NM5G I assume that's mostly because the gear train is a back-driva
Let's see... 90 degrees in 5 seconds extrapolates to 360 degrees (1 rev) in 20 seconds, or 3 rpm. I understand most of those prop pitch motors have about 1000 to 1 gear reduction, so the motor must h
If it were my tower, I would replace all of the guys and be done with the problem. If the tree did not bring down the tower, climbing it will not either. I would prepare the replacement guys and haul
I would not do what you are talking about. A living tree will tend to separate the tower sections over time. 73, Keith NM5G Does anyone know how much horizontal movement is considered acceptable at t
Well hooray for you! I turned 65 in January and have 4 more towers to put up, one a 200 footer with stacked 4el 40M Yagis. I would be climbing now except for an unexpected triple bypass heart operati
There are no problems with the rivets in my F12 antennas (C-4XL x 2, C-3 x 2, C-3S, several others). I have heard of problems but I think they are associated with extreme weather conditions. The orig
What other tri-banders have you owned/used? How does the TA-33 compare in the K7LXC/N0AX book? 73, Keith NM5G I will put my mosley ta-33 classic againt the 3 el ir or c31 force 12 any day and come up
I see the new ARRL Antenna Book (21st edition) is out. I have the one that is two years old now. Wondering if it would be worthwhile to get the new version. Anyone know/comments? 73, Keith NM5G _____
That's easy to explain in one word: spouse. 73, Keith NM5G Why buy a house where your neighbors can have control over what antennas you put up? Someone please explain? I have never been able to under
you with a very messy and hard to work with end. This is not right. The bolt cutter leaves a very clean end. 73, Keith NM5G _______________________________________________ __________________________
