Terry, The BL2 is a current balun. You will have to depend on others for an enclosure, I don't use one. W8FGU has an enclosure, but it is not weatherproof. 73, Don W3FPR On 3/10/2016 1:18 AM, Terry Brown wrote: I have just ordered a BL2 balun kit. I assume it is a voltage balun switchable

I have just ordered a BL2 balun kit. I assume it is a voltage balun switchable 1:1 to 4:1. I did not see any notation whether it was a current or voltage balun. One of the things I need is an enclosure for the balun. I would be interested in what others have used for enclosures, especially ones

Gary, Those two 80 foot 'counterpoises' are doing you no good at all. run some wires off the ground and insulate the ends, cut each one to be a 1/4 wavelength at a band of interest. If you have to run them in a bundle, keep the ends of the shorter ones separated from the rest of the wires by

I recently built a BL-2 Balun. It is connected between my Palstar AT1KM tuner and my doublet antenna. The antenna consists of a 100' wire up 25' and fed by 95' of 600 ohm open wire feeder. I'm using the 1:1 setting on the balun. There is a 4 section of RG-213 between the balun and a coax

Gary, Balun heating is normally caused by attempting to feed a very high or very low impedance. Have you tried the 4:1 position? It may help, so do try it even though I would believe the antenna system feedpoint impedance where the balun is connected may be in the range of thousands of ohms

PS I believe the BL-2 is rated at 150 watts so running at 125W is already at the limit even when it is placed in the ideal point in the circuit ... (50 ohms resistive). Place it in a point in the circuit where the resistance varies up or down from the ideal of 50 ohms and then make

Yes, you are reaching the curie temperature of the core. At that point it's magnetic properties change dramatically. Of course that heat comes from RF that is becoming heat instead of being radiated by the antenna. A bigger core isn't the answer. You'd still be losing the same amount of power
