Hf Antenna Question
"David G. Nagel" wrote in message ... Chris W wrote: I have been looking at the MFJ-1622 antenna. Part of the instructions for antenna set up, which you can find here.... http://www.mfjenterprises.com/man/pdf/MFJ-1622.pdf say to roll up about 30 feet of coax into a 12" diameter coil. This they label as a choke. This just seems like a "duct tape" solution to me. Is there a better way to accomplish the same thing? Would a few ferrite beads on the coax do the trick or do I just have no idea what I am talking about? P.S. please check out my new Ham Radio Repeater Database web site. http://hrrdb.com Chris; Your best choke is about 30 feet of coax rolled up into a 12" coil. This is not a duct tape solution but one that has been used for decades. It is the cheapest and easiest choke you can use. Others are better but not easier. Dave WD9BDZ I agree that the coiled up coax is a good way to go. As far as cheapest , with the price of good rg-8 size coax the cost is now about the same as the ready made chokes with the beads on them. If you factor in the cost of a ready made center insulator for a dipole the cost could be more. Also 30 feet of coax can be another heavy weight to support. |
