This Balun with mountingplate is a very good design to make your own wire dipole.
The problem with most baluns out of the store is that there is no easy way to mount it.
This Balun has an alluminum mounting plate 5mm thick, and a pressure equalizer for ventilation so that condensation is excluded.
This 1:1 ratio current Balun is the best solution for feedline isolation and choking.
Designed for those who want the maximum isolation and choking across the full HF spectrum. This Balun has two 2 cores in a stacked configuration to maximize choking impedance on HF bands from 1- 30MHz.
Transformation and power handling (up to 5KW) are excellent while providing a choking impedance that exceeds 8000 ohms.
Even on 160 m the choking impedance is 2000 ohms, and 3300 ohms on 10 meter.
Enclosure : Polycarbonate IP67, 100% UV resistant.
SO239 Connector : Silverplated.
All hardware Stainless steel.
