My amateur radio station at IK4AUY  and  IR4B,  is composed by:

set-up a)    and    set-up b)
set-up a):
HF Antennas from sept 2008 on: 6-10-12-15-17-20m.            3 EL. ULTRABEAM Antenna (4El on 6m),   the lower one
                                                    6-10-12-15-17-20-30-40m   2 EL. STEPPIR ant with 30-40m single element kit,  above the 3EL 
                                                    2m                                      4 EL. TONNA,  mounted on top of all
                                                    40-80 meters  one mor-gain dipole, 20 meter long with 3 closed spaced wires and center 
                                                    fed with coaxial cable, for limited space)

.

both antennas 2 EL STEPPIR 6m to 40m (with 30-40m rotary dipole) and below 3 EL 6m. to 20m. ULTRABEAM Antenna with 4 EL on 50 MHz


Previous antenna before august 2008:
10-15-20 meters  one Hy-Gain TH7 up about 17 meters from ground, top of  home roof.
12-17-30 meters  one rotative dipole by Cushcraft D3W below (because we have added it
             above the TH7)  at 90° (to minimize mutual pick-up with the three bands yagi)
VHF antenna:  144 Mhz  5 el short yagi by Fracarro mounted top of TH7 at  18 meters from ground.

set-up b)  - at country qth, flat area:

HF antennas:  10-12-15-17-20-30-40  one vertical antenna  by Cushcraft R7, at 2 meters from ground.

                     40-80-160 one vertical Butternut HF2V antenna heavily toploaded with 4 equal length 
                     sloping wires, each  about 5 meters long, ground mounted with 5,  20 meters long, radials.
                    
Rx only antenna: 40-80-160 with one direction only Beverage about 177 meters long, at 2 meters from
                         ground.  

I use our own designed SRC-02 Front-End unit (with passive RX passband filters, pre-ampl, variable attenuator and ant 1, ant2, RX antenna only switching control).

RIGs:              -  Yaesu FT-2000 (PEP2000 firmware upgraded, see my review page, click here (from Oct 2006)
                      -  Yaesu FT-897D (SN. 1/2009,  new July 2009)
                      -   Kenwood TS570DG <<<click here for ON4SKY/ LX4SKY review, and audio files in page 2 DSP)
                         
Other RIG:      -  N. 2  CDG2000 home built 200W Transceivers (SN.01 built in  2006,  SN.02  built in 2009)
                       -  I4FAF Home built  100W trx  (as back-up rig, second receiver only)
                       -  Drake C Line in beautiful shape, got it new in early 1980.
                       -  Atlas 210X,  like new, only one owner.

Amplifier:       One, home built by I4FAF,  4CX800A tetrode tube linear amplifier for HF bands, legal 
                        limit power 500 Watts,  only  if necessary.  Two more 4CX800A linear ampl, as spare one.       

PC:                  Pentium and netbook lap top for real time logging with  QART TEST by IK3QAR,   CT10DOS  by K1EA, log  with Easylog5

CW Paddles:    Begali Simplex, Bencher.

 Wattmeters:    TelePost INC  LP-100A (N8LP),   Coaxial Dynamics 83000-A,  Drake WH7.
