I've been unhappy with the performance of my NE beverage which often has been no better than whatever vertical or other antenna I have been transmitting with. At one time my beverage ran NNE at 15 de
I suspect the cores in the TV type balun were of the wrong mix for HF, Doug. That would account for some of the losses and SWR you experienced. CU in the pileups!! (((73))) Phil, K5PC -- FAQ on WWW:
Hi Doug, I've been winterizing my Beverages lately--making them longer, improving their feed and putting up new ones. I have gotten tired of replacing balun matching components destroyed by lightnin
SNIPS Be careful here Doug. The core material and the windings are very important to good performance. Many of us have had excellent results with a FT114-61 core and 16 turns #24 quadrifilar; that gi
While that does test the balun for impedance, it does NOT test it for loss. Many books recommend the WRONG core material for baluns, The cores have too high an initial permeability, some as high as
Amidon has a detailed catalog dated April, 1995 which they sent me for free although it has $8.00 on the front. It has technical and ordering data on their entire product line of iron and ferrites. I

SNIP Are you saying Amidon does not OFFER these mixes? What gave you the idea that I said they MADE anything? I only used the examples to stress a point that all cores are not equal. I would certainl

Hi All, To further complicate the problem, the type of transformer or balun and the power level also affects core selection. Carl is certainly correct, but another important fact is permeability of a
