  • Hamfests in 2018 3. 12. 2018

    In November we were on the last show in this year. Our team visited 21 shows in USA, England, Germany, Italy, Spain, Switzerland, Belgium, Portugal and in the Czech Republic. It is the most hamfests in the history that Mastrant has attended. We were very pleased to meet you and hope to see you again in the future!

  • Camouflage ropes 2. 8. 2018

    We started production of "Camouflage look" of two sizes of Mastrant-P – called Mastrant-C. It is targeted for customers who need "invisible" guying in specific environment. The main color is tan with brown “dots”. They are available in sizes "3+" (3.5 mm, 9/64") and "6" (6.2 mm, 1/4"). 

  • New size of "P" rope: 3.5mm (9/64") 30. 7. 2018

    We started production of new size of rope Mastrant-P which fills the gap between "size 3" (diameter 2.6 mm) and "size 4" (diameter 4.4 mm). It is "size 3+" and has diameter 3.5 mm (9/64"). Breaking strength is 300 daN (about 300 kg or 660 lb.).
