Sri to hear that your tower had difficulties. My HDX-672 was installed by me and then I put a M2 3 element 80M beam on it by myself...more to see if I could do it single-handedly than anything else.
Here's the lash-up: a mostly vertical 1/4 wave vertical up through a fir tree over 27 radials that has best SWR (1.0 : 1) at 1828 when measured at the feed point. After running roughly 350' of RG8 eq

There will be an informal, interactive presentation by members of the recent FT5XO DXpedition concerning all aspects of the trip. This will happen Friday evening 9:00ish until late in the Beckel Room
What is the highest elevation you can get the line up and over with a slingshot/reel combo? With just the slingshot and the 60# test line pulled off in front of me with out a reel I can get up to abo
I've had more crank-ups destroyed than most. Some were operating error and some were Mother Nature smacking me around some. K7LXC has some pix of what happened to a crank-up when a thunder storm cell
I plucked 70' of Rohn 55 with a rotating bearing 20' down from the top and put it on 40' of Rohn 55 that I already had up. The Rohn 55 did fine with some flexing. The skill is in the crane operator's
Yo, That tower is unsafe and needs to be dropped. Too much movement has stressed the joints between sections and makes it very dangerous. A rogue, tall Maple tree attacked the 60' Philly guy on a 120
I had a stick of 120' of Rohn 25 guyed every 30' up with Philly. A large, previously thought healthy maple went to ground due to wind & rain. The maple took out the eastern guys at 30' and 60'. The t
Hi Mike, Favorite products for wire tree antennae here are: pneumatic air gun antenna launcher, 3/16" Dacron rope, 12 GA stranded insulated wire and patience. I have 2- 1/4 wave Comtek phased vertica
Yo, My friend, the crane guy, clean lifted 70' of Rohn 55 over to me atop 40" of already erected tower that had a rotating tower bearing at the 50' level of the section that went on top. No problems
Yo, That has been looked at by guru Rudy Severns. Google N6LF and click on design of radial systems. It is very easy to spend hours absorbing what Rudy has been studying. 73 and I remain, Lew W7EW/W7
Yo, I recently bought the MCPT 78 from Kollman Radio, along with a slug of other stuff. The price was around $33. They also listed the prep tool for the 1/2" hardline also which was around $24. They
Yo, I think you're done. When I put up my various and sundry sizes of US Towers I made sure that the base plate that sits on the threaded J bars into the concrete was level by adjusting the big-ass n
Yo, Several years ago I left my US-Tower 589 fully extended so as to work KH6 on 2M. A thunder cell touched down or a tornado or some nasty wind folded over the middle section. I called US Towers and

Yo, So, several years ago I had a 6M stack with 2 antennas. The feedline from the stack box was 50 ohms for a short distance (turning loop) then all the rest of the way into the operating position wa
Yo, My QTH is the highest point of a ridge, line of sight of several different installations for paging, police, fire and probably interstellar communications. Notch filters before or after the pream
Has anybody here devised a way to use a quadcopter with some sort of release relay to put a light line over a tall tree for a wire antenna? I've used a pneumatic gun in the past with great success bu
