A great balun for windoms, OCF antennas >60 feet over ground, Hertz and folded dipole antennas, T2FD etc. Dual core, Ruthroff style balun. Choose version with side eye bolts for wire attachments for OCF dipole use.

Dec 26, 2024 · Requiring a balun to feed a balanced antenna from an un-balanced line with a impedance step up from 50ohms to 300ohms, a 1:6 Voltage balun design using a L15 ferrite toroid cores was selected. Construction

Dec 26, 2024 · The Version 2 1:6 voltage balun using a FT140-43 Ferrite Toroid Core represents a very efficient balun for a frequency range from 0.5MHz to 30MHz at a power level of 100W PEP. Power Handling

Utilizing two (2) individually wound 4:1 current baluns cross connected in series/parallel, a 6:1 design is created that will handle high power from 3.5 to 54 MHz. Good choice to feed multiband antennas such as off center fed dipoles typically at or above 60 feet horizontal.

Balun, 6:1, Transformer 1.5-70MHz, 1kW SSB, 700W CW, 300 Ohm, FT240-43 Toroidal Core, SO-239 female, 2 Terminals, Each. Find Baluns, UNUNs and Chokes 6:1 Ratio and get Free Shipping on Most Orders Over $99 at DX Engineering!

Bullet™ and Super-Bullet™ Baluns and Ununs are 500/1500 watts PEP rated, purpose designed for portable and stealth installations for all antenna types. Easy to deploy, heavy and sturdy enough to be thrown over a tree limb with ease and robust enough to run demanding digital modes like FT-8/FT-4, RTTY, and PSK31.

Dec 26, 2024 · BALUN 1:1 CHOKE & 1:4 BALUN HF ladder feed-line to coaxial cable combination choke and 1:4 balun. (0.1MHz - 30MHz). BALUN 1:1 CHOKING Choking balun for lower HF and MF bands.

Balun is an acronym for BALanced to UNbalanced, which describes certain circuit behavior in a transmission line, source or load. Most communications applications deal with two-terminal sources, transmission lines, and loads. This includes coaxial cables, open wire lines and systems working against earth or a ground plane as the "second conductor".

Feb 17, 2025 · With a 4:1 feedpoint transformer/balun system, you can use 75ohm coax perfectly. Most consumer-grade 75ohm coax can't be soldered, so you'll have to use an F-connector and a converter. Any residual mismatch is best dealt with an L-network (very low loss if well constructed) typically used in ATUs.
