Jeff, Please check the head markings on your galvanized Grade 8 bolts. If they're actually Grade 8, they'll have 8 radial lines marked on the head. The reason I ask is that I've never seen a galvaniz
Hi Larry, oops... of course Grade 8 bolts they have six radial lines. 73 Frank W3LPL -- Original message -- _______________________________________________ ___________________________________________
Jim, You don't need anything other than the two thimbles. Just link them together like two links in a chain. 73! Frank W3LPL -- Original message -- _______________________________________________ ___
Experienced tower climbers use a mental safety checklist every time they reposition. It takes only a few seconds. Here's another important mental checklist item for every time you reposition: * * * A
Arliss, I'm concerned that you may be building an overloaded tower! Have you analyzed the loads on your 190 foot tower from the additional long boom (50') Yagis you're planning to install? If you don
Dick, One of my transmitting antennas is a 1/4 wavlength-long 160M inverted-L with direct 50 ohm feed, and it works just fine. As long as your transmitter can handle reasonable VSWRs, up to perhads 2
Peter, RG-8 will work very as a gamma match capacitor on a 40 meter Yagi. If you can get the correct size aluminum tubing, you can simply insert the RG-8 dielectric into the gamma tube. I did this fo
N3RS uses a forty year old 40 Meter HyGain 403B "DX Long John." Sig is fully competitive with every other big gun on the band. In addition to DX Long Johns, Hy Gain also manufactured a knock-off of t
Thanks for the great K2GL photos Bob, but up with those photos? It looks like Buzz invited a gang of children to operate that contest! 73 Frank W3LPL -- Original message -- __________________________
US Antenna Products -- and their sister company US Tower Services -- are owned by W4NRS and K3GJB. Most of their senior managers are also hams. The heavy rotator on K2GL's 80 meter Yagi was probably
The W3NQN filters are excellent. I use them between my transceivers and all of my amplifiers and they do an excellent job of eliminating out of band spurious signals and noise from the trnasmitted si
The tower is actually 205 feet tall, therefore tower lighting and painting requirements are inherited with the purchase. http://wireless2.fcc.gov/UlsApp/AsrSearch/asrRegistration.jsp?regKey=606555 73
So we're wondering why this 200 foot AT&T tower, building and surrounding land are so inexpensive? Anyone who has ever travelled to Washington County, Maine will surely recall the extreme poverty the
Scott, The T2X and Ham series manuals (including mounting templates) are at: http://www.hy-gain.com/manuals.php The mounting patterns are identical, except: - the T2X uses a six bolt pattern with 11/
Larry, Unless the terrain in front of your antenna is sloped more than two or three degrees for at least several thousand feet, your antenna will work very well at 115 feet. In two or three years --
If you search the Towertalk archives, you'll find some hams (e.g., K7SV) had problems with stacking the KT36XA and the 40M4LLDD. I'm not sure that the smaller Prosistel is a good choice for turning t

Very important safety reminder: Drilling on a tower can easily cause serious eye injury, I know two hams who suffered serious injury from this kind of work on a tower. Be sure you wear eye protection
Will, Have you considered suspending an inverted-L, or a T vertical, between your towers? Unfortunately, you're likely to have parasitic effects between any vertical and your two towers, both of whic
Oops... While stainless steel screws may perform useful mechanical functions if applied correctly, they can NOT perform electrical functions at RF because of skin effect. 73 Frank W3LPL -- Original m
