HF End Fed Antenna UJM-EFHW-80-10-1kW+ 130 ft long For Sale

\'s Top End Fed & Portable Antenna Seller
PLEASE READFirst, a bit about Nelson Antennas.I have been here on since 2005. While I have built and sold literally tens of thousands of antennas, I have chosen to keep my operation a 1 man show. I only trust myself to manufacture, build, tune and test antennas of my quality. I build every antenna as if it were for my own use.I am not one of the many that have copied another antenna and started pedaling them while not fully understanding them. Most that copy other antennas, miss things in the fine details that really set the antenna apart. Many circles pedal common materials lists as though there is a simple copy and paste method that ends in the same product every time. I can sure you, this is not the case and there are many fine details that are almost all overlooked or totally misunderstood that wil result in losses of efficiency and effectiveness.Every antenna I build, is done by my own design, which includes limitless hours and finances in R&D, to find the highest efficiency and effectiveness I can get.I don\'t skip on anything. There are no compromises when it comes to what works best for the wanted ouutcome.You know I have been here for many years just by looking at my dated pictures in the listings, which I hope to modernize at some point soon.
I also send a sheet with every antenna with online groups for buyers to join where you can interact with my customers and myself for anything from showing off your setup and DX contacts, to asking me or any of my customers for help with any questions.PLEASE READ THE FULL LISTING AND ASK ANY QUESTIONS YOU HAVETHIS IS THE UJM-EFHW-80-10-1kW+After many requests to add a high power capable unit to my end fed half wave arsenal, here it is and they are TALKERS! Now you can use exactly what I use at my QTH. And the best part is for what I know is a better unit, mine are $60-75 cheaper.PLEASE LOOK AT ALL PICTURES TO SEE THE DETAILS AND CRAFTSMANSHIP!This unit is sporting a massive transformer in a 3.5\" X 4.5\" X 2.25\" housing and it provides EXCELLENT efficiency on all HF bands.
Transformer is wound with \"heavy dipped\" 14AWG magnet wire. Unit comes vented as seen and with a transparent lid.This sale is for a true, 49:1 half wave end fed antenna for 80-10 metersThis antenna is rated at 1000W+ PEP and a conservative 250W digital FT8/CW and is PERFECTfor both portable or permanent installations! I have been working mine very hard for the last few weeks at legal limit without issue or ANY excessive warming. That said, I am conservatively selling them rated for 1kW. Let me start with a little hard to find honesty. I am the type of operator that if I see a 1.6:1 SWR I just tune it to a 1.1:1 and start having fun even though 2.0:1 or less is considered fine without tuning on HF bands. So, I will not lie to you or mislead my customers telling them this antenna will work every band without a tuner. I have seen first hand, what is considered a commercial version of this antenna claim no tuner needed yet when installed just the way recommended we see VSWR\'s from 2.8:1 to 3.9:1 on some, (not all), major bands advertised for. This is unacceptable and is in no way a no tuner needed antenna.
This antenna, when deployed in a decent area without being to close to large objects like houses, buildings etc will indeed have a good SWR but tuning to a 1.1:1 is just always a good idea for your equipment in my opinion. I am a seller who likes to under promise and over deliver.Band *Typical low SWR*10m 1.4:112m 1.3:115m 1.1:120m 1.1:140m 1.1:180m 1.7:1 75m Will need a good tuner.
**Your millage may vary some** as no 2 installations are identical. This antenna comes complete with 130 feet of stealthy but strong 16AWG MARINE tinned copper stranded insulated wire that will handle well in excess of 1500W. Marine wire is tough, tinned and made for harsh environments. Also comes equipped with a UV dog bone insulator and all Stainless Steel hardware throughout. The box is sealed with a foam gasket and a very high quality SO-239 connector as well.Antenna is resonant and works 80,40,20,15,12 and 10 meters.
With a decent tuner you can also tune 30 and 12 meters and 17 meters as well. I do also have a 40-10 meter version listed for sale and is only 65 feet long.One of the great things about this antenna is that the height you mount it will have a smaller affect on SWR than other antenna types. This gives you a large flexibility in your installation.
One huge advantage of these antennas is that they typically have very good \"ears\" with a low noise floor!
As you can see from the picture the antenna box does come with the mounting eye-bolt wired for optional ground. You are not required to but I recommend a good straight earth ground be wired to this lug. That way, any static etc has a quick, straight path to earth. In other words, direct earth grounding that lug can sligtly decrease your S-meter noise level. NO RF CHOKE NEEDED IN MOST INSTALLATIONS! Most users will find no rf issues and find no rf choke is needed. That said, using a GOOD rf choke is always good ham practice.Another advantage of this antenna is the endless ways you can deploy it. I recommend a simple sloper installation and you can mount the box close to the ground 3-6 feet, with your element sloping upwards and outwards from there. When installed as a sloper you will see fantastic results if you can get the far end of the element up to 25\' or more. That being said, you can install this antenna: horizontal, vertical, inverted \"L\", zigzag and more with very minimal to no changes in tunning.This is a very simple antenna to install and no extra instructions are necessary but if you do have any questions please feel free to ask. Simply secure a cord to the mounting eye-bolt and stretch out your element for your installation and secure it.
Great for ALE HF-link stations, NVIS, MARS, ARES, EMCOMMI have produced and sold more than 15,000 antennas here on alone and still maintain a 100% positive response for a reason. everything I make and send is made by myself, no help allowed and only made as if it were as my own antenna. I feed my family this way and so my customers ALWAYS get the highest level of quality and customer service I can provide. To put it simple, my livelihood depends on it.
If anyone has an issue at all, please just send me a message through and I will take care of you as I have done on here for over 7 years now.
I also have 9:1 unun Random Wire Matchboxes that are designed to be used with a tuner on all bands with a *random* length wire as well. PLEASE LOOK AT MY OTHER LISTINGS!73KD8UJM
