*Retrofit BalunsUse our "retrofit" baluns to improve the performance of products made by other manufacturers. Following an ineffective, Voltage-type balun with a Current-type Line Isolator can greatly enhance antenna system radiation pattern and improve feed line isolation. Installation is easy - simply connect the Line Isolator between the antenna's balun or feed system and your coaxial feed line. That's all there is to it. Next time you take down your antennas for maintenance, be sure to install a T-4. Coaxial CableFor wire antennas, I suggest using RG-8X or RG-8X Plus. RG-8X's light weight and the resultant reduction in strain on antenna components can prolong the life of your wire antenna system. For all other antenna systems, I recommend using the best, low- loss coax that's practical for your antenna system. My first choice would be RG-213 Plus unless the application is VHF and the runs are longer than 75 feet. For VHF and some 10 meter applications, choose one of the very low loss coax types like SuperCable, ExtraFlex, Super 400, etc. |
