The Steppir is in the air. I have poured the base for a 50' Rohn 25G. The hole for the base was dug 3'x3'x5'. The 1.5 yards of concrete, 500 lbs of gravel and 120 feet of 1/2" rebar make up the base. A 4'x4'x6" thick pad finishes off the base. The pad is intentionally wider on one side to provide for a base for my portable generator. The house brackets in the picture above were installed to maintain the tower in a level condition during base construction. They will remain in place to give the tower as much stability as possible. The tower is guyed at the 45 foot level with Phillystran guy wire. I really want this tower to stay vertical!! So far 60 mph winds have not even caused the tower to visably sway.

The window well to the right of the tower leads to the shack. An MFJ4603 connector panel mounted in the shack window brings the coaxial cables in. A series of 5 ground rods tie the system ground to the radials installed in the back yard. A Georgia Copper ground plate is used as the system star ground point.

 

I installed a 3 element Steppir, a 80 inverted L, and a 160M trapped Inverted L. The Inverted L's sit atop 20 ea 40' to 130' radials atached to a DXEngineering radial plate and fed through the separate ports on a Palstar HF-Auto tuner.   I have also installed a Hygain AV640 vertical antenna that is used as a back up/multiplier antenna.  Antenna Switching is done through a DX Engineeing 8 positon remote switch with an Ameritron RCS-12 controller attached to a Green Heron Everywhere base staion for control. For satellite work, I use a pair of M2 eggbeaters and an Advanced Receiver Research 70cm preamp. For HF, I currently run a pair of Elecraft K3's.  The main K3 has a second receiver and uses an Alpha 8410 amplifier attached to the Steppir and inverted L's. The second K3 uses a QRO Technology HF-2000 amplifier and connects to the AV640. Both radios have P3 panadapters. The main radio also has an LP-Pan.  I use the LP-Pan primarily for CW skimmer but do run NaP3 once in a while. I am attempting SO2R from this location and have added 5B4AGN tx filters to both rigs and a pair of Top Ten Devices 6 way switches with coaxial stubs to improve isolation. A Microham MKR2+ provides headphone, cw paddle, digital sound card and fsk control switching between the 2 Elecraft rigs.  For Satellite, I run a pair of Down East Microwave transconverters and the K3's.

Grounding was placed high up in the priority list.  One inch braid joins the ground rods (a total of 5) to the Georgia Copper ground plate in the house. All equipment connects to the ground plate with 1/2" braid. So far no tvi or rfi to anything in my house that a few ferrite beads couldn't fix!!! Polyphaser lightening arrestors are used in all coaxial lines.

I run SSTV, JT65, RTTY, PSK31, V4CHAT, CW and phone. I use FLDIGI, JT65-HF, MMTTY, MMSSTV, MVARI, MULTIPSK, MIXW, and PC-ALE for software. I use DXLabs for day to day control and logging.  I run N1MM+ for my contest logger.
