Doing some major antenna work here. For the past 10 years I’ve been using a 92 foot long doublet, up 45 feet, fed with home brew 600-ohm ladder line. From the back of my K-Line / KX3 / KX2 I ran about 10 feet of Belden 9913 coax out the window to this balun, under the eves. From there, 110 feet of that ladder line to the antenna. Worked really well but my radiation lobes were not going where I wanted them and I had limited support structures. So, the doublet came down this weekend and was replaced with a 40 / 30 meter Skeleton-sleeve dipole.
That means this balun is excess to my needs. It is a Balun Designs model 4114T 4:1 dual-core current balun; rated at 5kW - I’ve never used more than 500 watts. It has an SO-239 coax connection on the unbalanced input and two studs with wing nuts on the output balanced side. It’s been mounted under the house eves all this time and has had very, very minimal exposure to rain. Some fading can be seen on the outside of the plastic housing, and a little black “gunk” from liquid electrical tape got on a small part of it - all cosmetic. It is in excellent condition - I’ve never had a problem with it. Photos available upon request. If you are looking for a great, high power 4:1 current balun for your antenna farm - this one would be your choice. Take a look at the BalunDesigns.com <http://balundesigns.com/> web site for this model and it’s specs. You’ll see that it sells for $89.95 new plus shipping (and maybe tax). I’ll sell this one for $55 - free shipping to any USA address - Priority Mail. Contact me off-list if you have questions. Payment can be PayPal ([email protected] <mailto:[email protected]>), cash, or personal check (one week to clear, please) Tnx & 73, Jim Bennett / W6JHB Folsom, CA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
