Setting the standard for VHF baluns

* A true, 4:1 current type Balun
* Two-core cross-coupled design.
* Good output balance.
* Special ferrites for high frequencies + 6 and 2 m
* Teflon components.
* Wide bandwidth with carefully controlled reactance characteristics.
* The same first-class construction as all "B" series HF baluns. Made to last for years.
* The original VHF 4:1 current Balun, using the same technology as the incredible B4-2KX precision HF balun.

At VHF frequencies, it is difficult to build a 4:1 balun that tolerates realistic operating environments where mismatched loads are common. Unless a balun is very carefully designed, you can expect poor balance of output and core saturation. New problems arise at VHF frequencies. Transmission lines must be very short in terms of wavelength, special ferrites must be used, and they must be effective over a very wide frequency range. Every construction detail must be carefully specified if each balun is to function as specified. We met and exceeded all expectations again with the B4-1KXV. At this time, I know of no other 4:1 VHF current balun on the market, and certainly none with the credentials of the B4-1KX.


The B4-1KXV VHF type balun is suitable for all applications requiring a 4:1 precision balun. It can be used with some types of OCFs, folded dipoles, folded monopoles or any application requiring an unbalanced to balanced transformation from 50 to 200 ohms.
