Academy has mostly sports equipment. They started out as Academy Surplus. I think it could be found at a sporting goods store that carries fishing supplies. 73, Keith NM5G What, please, is "Academy"?
Actually, I have the latest Antenna Book with HFTA. I am looking for someone to relate actual experience using a 2el 80 at or near this height. 73, Keith NM5G Or buy a current Antenna Book and use HF
It eventually gets to be a bit stiff, but a piece that has been up for 10 years is still holding up well. 73, Keith NM5G Is that stuff designed for home use and to be "environmentally friendly" and d
If budget is unlimited, use Andrews 7/8 Heliax from station to tower base. If not, run LMR400 instead. From there run regular flexible coax up the rower. I use Belden 9913F7, but there are many choic
One other note to add... I think this tower was not designed to handle a large rotating antenna. The bracing is flat, which is great for climbing, but not good for twisting. 73, Keith NM5G $3500 for
Bring in dirt and build a mound at least 5 feet up from existing elevation. Put the 27 foot tower on top. Hopefully no one will notice and complain, but if they do, at least you will be legal. This w
I have found the "comfortable" bending radius is about 1.5 feet (3 foot loop), but you could get a loop quite a bit tighter without distorting the center conductor. I treat it similar to 1/2 inch har
I would not do it. I would use 213 or 9913F7. 73, Keith NM5G Can standard LMR400 be used for the rotator to tower loop which has repeated bending or should flexible LMR400 be used? k7puc ____________
Silicon rubber fusion tape is good stuff to seal out moisture for a coax connection. $1.97 for 3 feet is kinda pricey. I buy mine from Home Depot on line for $4.98 per roll. Not sure how much is on a
That is indeed interesting. Thanks for sharing. How tall is your mast? I spent about 3.5 hours up on my 150 foot tower this morning. Put up 2 new antennas. Wore out before installing coax and stack e
I use the WB0W gin pole and 1/2 inch Rhino rope. I think the Rhino rope will also work with the Rohn gin pole. http://www.wb0w.com/wb0winc/ginpole.htm 73, Keith NM5G --Original Message-- From: towert
reference for how to use tie wraps? My last batch of pre-formed guy grips for Phillystran came with ty-wraps and instructions on how to install them. I thought it was silly but put them on anyway. I
I would not use the stretch factor of Phillystran as an argument to not use it. The amount of stretch in an amateur installation is negligible. If you are going to keep using steel and plan for multi
How do you know that? When I cut 6700lb Phillystran, it takes a bolt cutter, same as 1/4 EHS rated at 6000lb. In fact, it usually takes more force to cut the Philly. What is the actual difference in
I would say it depends on the tower, antenna and mast. We used a 1/4 EHS tram to take down an old C-4XL and replace with a new C-4XL at 152 feet. The tram was attached to the mast about 4-5 feet abov
For Philly, wrap one turn of each leg at a time. If you wrap one complete leg, then the other, the Philly will squib out between turns because it is so flexible. 73, Keith NM5G differently from the E
This is not true. All of my Philly was done without tensioning the cable. However, the thimble was placed in a large bench vise to hold it and the grip steady while wrapping around the Philly. 73, K
Your tower is not bent. The two guys now holding it firmly are pulling it out of line. Your EHS is not stretched either. You can reuse it as-is. Same for the turnbuckle. You don't need clamps to hold
The WD in the name stands for water displacement. It is intended to be a penetrant that displaces water and thus is ideal for metals that would rust if left in a moist atmosphere. For example, is it
That is great stuff. However, the moly is intended for applications involving high heat (e.g. high rpm). DuPont also makes a Teflon white lithium grease in a spray can that would work as well. Not su
