Hello Ham friends. I started in radio in the mid 1970s. I am a retired Florida firefighter, IAFF 2794, and did constant radio communications over my 27 years with the FD. I enjoy many aspects of HAM radio including rag chew, DX, and contesting. 7.195 is my home in the evenings stop by and say hello. So 73 to all and I look foward to making lots of contacts and friends.

Mobile : Yaesu FT-890, Hustler antennas.
Base Antennas :
Rohn 40' Push Up Pole, 2 meter G.P.
Tower #1 - 40' Rohn 25,
Tower #2 - 50' Rohn 25, Homebrew 80 meter wire, 10 meter G.P.
Tower #3 - 75' Rohn 55, Mosley Pro 67-C3 - 8 band 7 element beam (see pictures below), Tail Twister Rotor, LMR 400.
Antenna analyzer hard wired to a switch so I can check all antennas preformance without using the radio.
Special Thanks To: W5IFN my Elmer, K4XS my contest Elmer, W8AMZ manufactured my first antenna a G5RV (Tom, now a SK) he will be greatly missed. N5SDO consultation on my towers, N0PWB and WX4CAZ my friends along with many others.
If you need professional tower work I highly recommend Dave N5SDO. Good on QRZ.
QSL - If you would like to send me a QSL card I would like to have it. However, at this time I am not sending them. So please dont waste a SASE.

God Bless You and God Bless America.
Florida being the lightning capital of the world requires special consideration.
Nothing is going to stop a direct hit from frying everything connected ,but, I try my best to keep it outside the shack. All coax leads go to a remote switch located outside the shack, The lead in coax, rotor control cable, equipment ground, and remote switch control cable are all surge protected and have disconnects outside the shack. All three towers, the service box under the tower, the remote switch, the equipment ground and the service ground are all bonded together. Static dissipator located 6' above Mosley Beam. If the equipment is not in use it is unpluged including the ethernet cable. I do not reccomend using a active well casing as part of the ground system.
My 2014 tower project. Rohn tower 55G 75', RT Razor Lift System, Mosley Pro 67-C3, and TailTwister rotor.
The Tower Crew
From left to right.
KK4TUO Leo - Concrete Forman and Assembly Tech
WV4R Walter - Owner, Tower Monkey and Assembly Tech
KK4ZDS Wayne - Excavation Forman, Electrician, Welder, Tower Monkey, and Assembly Tech
Here is what I started with.
6' X 6 ' X 5' Base. 6" above grade and the bottom 6" is gravel for proper tower leg drainage.
Tower base was to far away for cement truck. Thank God for pumps. Total of 10 cu. yds. concrete.
5.5 cu.yds. concrete in base 21,000 lbs. All site work and rebar to Rohn specs.
Custom guy wire anchors in 4' X 4' X 4' hole with 2' concrete, 1.5 cu. yds. 5,700 lbs., in bottom of hole then back filled.
Now we wait 30 days for concrete to cure.
Assembly of Rohn 55G with fresh paint. Rust-Oleum 7000 System - Cold Galvanizing Compound.
Dielectric grease on every joint makes for a good ground. The tower will also come apart easier if neccessary.
18 volt Impact wrench comes in very handy.
70' assembled and ready to go.
Crane arrives on site.
KK4TUO Leo supervising crane operations.
Crane straps are attached to tower one section below top.
Me getting the crane unhooked and straps off at 65'.
Me rigging temporary guys'.
Looking up the tower.
View from tower at 75'. The power lines are 1/2 mile away and cause no interferrence.
Me working on RT Razor lift system some fresh wheels and paint.
RT Razor lift set on tower. Check out rtinnovations.net
Conduit in ground for coax and rotator control cable. Also romex for 110v at tower base.
KK4ZDS - Wayne, the super human backhoe does it again.
110' conduit from shack to tower. Total 210' coax including 18' for choke under antenna. Jeffa Tech LMR 400.
Distributation box at shack. Coax, rotor control cable, and romex for 110v at tower base.
Remote antenna switch with surge protector. Disconnects for switch, lead in coax, and rotor control cable.
WX4CAZ Joe pulling cable.
Wayne welding bracket for electrical box at tower.
Electrical box at tower. Alpha Delta (Polyphaser type) surge protector for coax. Morgan Surge Protecter for rotator control cable, and 110v power for Razor winch. Enclosure and extras provided by KF7P Metal Works. Check out KF7P.com
Grounding system staked out.
Water jetting to sink ground rods. The ground rods are 6 - 8' x 3/4" copper pipes.
Trench with ground rods and #4 copper wire. One run attached to each tower leg.
Ground wire attachment to ground rods.
Neatly placed in sprinkler valve boxes.
Nice, clean, and accessible.
Ground system attached to tower. Ground wire is in insulator to avoid abrasion and contact with concrete.
Tower legs are wrapped in stainless steel to prevent reaction from dissimilar metals. Copper clamp to galvanized tower leg.
Me drilling custom plate to mount wench to tower for Razor.
Mast 6061 T6 Aluminum 2" OD .375 wall thickness.
Four big boxes arrive from Mosley and unpacked. Some assembly required. Mosley made this assembly easy with great color coding and predrilled holes. Some fine tuning was required. Mosley customer support is very good if needed.
Me with the front driven element 44' long .
Boom to mast bracket.
Stacking one element at a time on 24' x 3" boom.
KK4ZDS Wayne on lower guys. The top 35' of the upper guys are Phillystrand. Everything else 1/4" EHS. All joined with the correct size Big Grips and insulators.
K4XS Bill tensioning guys. Bill also provided much appreciated technical support.
Me headed up for a few final adjustments.
Everything looks good.
Home brew static dissipator mounted 6' above antenna boom. If store bought this cost approx. $500 if you could find someone to sell you one. We built this one for $150 using aluminum tubing and stainless chimney brushes.
The Pro 67-C-3 project finished at last. Three months from start to finish.
Thank you to everybody that contributed to this project it could not have been done without you. Projects like this give you a greater appreciation for all the knowledge that other HAMS have to offer. And then in turn we hand down to others.
Special thanks to KK4ZDS, Wayne, my friend and right hand man. Perhaps I was his right hand man, hihi. The countless hours and late nights we spent working on this project together was a great experiance, very educational, lots of hard work, and we had lots of fun along the way.
CAUTION the below links are companies advertising their products ,but, have some good information on dissipators.
These companies don't want to sell us their products. They think were to stupid to do our own engineering. Build your own.
