I was born December 05th, 1959. With 13 I got in contact with amateur radio and in the age of 16 I got my license. I always was and still am very much interested in dx contacts. Furthermore my passion is the designing of short wave antennas. In June 2001 I founded the company OptiBeam Antenna Technologies, and nowadays OptiBeam belongs to the more well known and bigger antenna manufacturers world wide. Since May 1999 I am married to my wife Diana who also works for OptiBeam.



OptiBeam shack, Tom, DF2BO sitting, the OptiBeam manufacturing                     The world's best 8 band antenna set up on a 36 meter/120 feet high rotating LUSO36XXEU

cooperation partner Mike, DD3OZ, standing behind.                                                 at OZ8X: OB804030x / OB21-3 / OB9-2WARC at 36,00 / 27,70 / 19,50 meters

OptiBeam OB18-6 at 73 feet

-> 18el (+ 8 hidden sleeve el 12/17m) /six band (40-10m) interlaced multi monoband system / commonly fed by a single

     coaxial feed line / 38 foot boom

-> 3el high Q coil shortened monobander on 40m/4el full sized monobander on 20, 17, 15, 12m /7el full sized on 10m, working

     like a 5el monobander

OptiBeam OB2-80s +OB2-30 interlaced on the same boom at 83 feet

-> OB2-80s: 2el 80m Yagi / 33 foot boom / element length 58 feet, shortenedby high Q coils plus a very efficient computer designed endloading /

     usage of the OptiBeam 4 step multi switch system to coverSSB in three segments -each 60 khz wide-plus 60 khz on CW

-> OB2-30: 2el 30m Yagi / active boom length = 13 feet / elementlength 32 feet, shortened by high Q coils / separately fed

=> see www.optibeam.de

the new OptiBeam 80m multi switch system

->this new 80m multi switch systemis installed at the centre of each 80m element, consiting of the relay box and two high Q loading coils

-> inside the relay box 3 high quality relay pairs = 6 relais in total, connected correspondingly to a defined amount of coil windings, allow a four step

    switching, 3 x SSB + 1 x CW, each segment about 60 khz wide

-> the control unit in the shack has to be connected to a 24 Volt source and a four wire cable (+ shield) has to be runup to the antenna

-> the system can handle up to 10 KW

=> see www.optibeam.de


Prosistel PST110D

-> 240 kg (528 lbs) antenna weight + 50 kg (110 lbs) mast weight and a wind load of around 5 m2 (54 feet2) are turned by the PST110D

-> the PST110D is the newest and strongest rotator in the Big Boy Rotators line, twice as strong as the famous PST71D
