aka572: Thanks for the video Stan but it only tells me how well the antenna receives signals. Now I would like to know how well others can hear your station. Maybe another video?
Tnx agn es 73
J Jarman: Love it! Thanks for posting. Great setup at the house as well!
kenwood8029: Really informative. I've been experimenting with there here lately and am beginning to like what I see and hear. Good job.
Audio Fidelity: Thank you for the reply sir! 73, Dave
stanscoyote: I believe it can make some difference but I never experimented with it. The tuner resolves any differences. I typically use around 25 feet and it's just cheap 52 ohm cable from Radio Shack. 73
m0ggk: Hi stan, I he you are well. Can I ask does the length of coax from your tuner to the antenna make any difference?
m0ggk: Hi stan,
stanscoyote: I bought two large plastic spring clips from Staples meant to hold thick sheafs of paper. Then, for each clip, I just cut a length of small diameter bungee cord, knotted it, slipped it over the mast (from the bottom) and adjusted the spacing to what I felt was a good working "wrap size". 73, Stan
Audio Fidelity: Nice job Stan! I appreciate the time you took to make this video. I have implemented a similar set up, and it's working great. I use the Spiderbeam 40' telescoping fiberglass mast, and I absolutely love it. Built very well. How exactly are the clips mounted onto the mast for storage of the wire? Thanks! DE AB7Q
stanscoyote: I prefer ferrite beads. An 8 turn coax choke affected my SWR negatively.
stanscoyote: The plans are online at the EARCHI website mentioned at the end of the video. The matchbox design and construction is no secret. 73, stan
Crobular I: Surely it needs a 9-1 UN UN toroid transformer though. 2.5" toroid and 18 bi-filar turns should do it.
gr8 shoot out. I would have had a coax choke on the half wave.
de n8zu good luck and good dxing
Peri Cosseboom: I have a 33 foot end fed wire with a Hawaii end fed match box. Very nice from 10 to 40. Particularity on 10. The guys with the big beams and 1000 watts are clueless and jealous.
sealsster: Great Video! Just waiting for my fiberglass pole to be delivered. If it arrives in time will be trying it on the Virginia QSO party this weekend.
stanscoyote: Does not need radials. Halfwave antennas have very high feedpoint impedances with correspondingly low current return requirements. The coax outer shield does the job in this setup. That's the appeal of half wavelength wires. Read up on it; worthwhile learning about them.
Raymond Burns: What about radials
De ray wb2mly
Kk Andretti: Thanks Stan..:) enjoyed the video also.:)
stanscoyote: It's an antenna for use with amateur radio transmitters and receivers where impedance matching is important. If you are a shortwave listener, your best bet is to throw up as much wire as you can: any size, any shape. The requirements for a receiver are vastly different from those of transmitters. Enjoy the shortwave bands.
Kk Andretti: Hi, I'm looking for an Antenna that would be good for all Bands, i'm just a DX'er, and just bought me a new Shortwave Radio to play with ...
Is this actually an Antenna or just a telescoping Pole..?
Thanks ... KK
Sean Ingram: That's a Good looking ELECRAFT rig.
stanscoyote: This comment and your earlier one are correct, Jimmy, and it's why QST policy is no antenna reviews! Too many variables to contend with. However, if everyone abstained from trying to share info because they could not do it perfectly, we'd have even less to go on. Hence, please note the use of the word "empirical' in my Youtube description: "Guided by practical experience and not theory". 73, Stan.
wx9dx: LOL:) Any antenna is better than no antenna:) But your compairison was way off base.
Jimmy, ARRL TC, WX9DX
wx9dx: Comparing one antenna against the other like that is not correct. The propagation of the transmitted signal and the angle of the received signal as they come back to earth differ. Also the polarity of the signal can change moment to moment during the trip from the transmitter site and the receiving location. If you notice a fade on an antenna switch to the other antenna and they might be coming up. Which is a fade because of a polarity shift from the Ion layer moving around. 73 Jimmy, WX9DX
2e0bax: There is always a way to get on any band in any building, view it as a challenge. I have enjoyed many portable activations as well as pedestrian mobile.
CW rocks, I'm not very good at it, but its so much more efficient.
As for antenna experimentation google my call sign....73 de M0GIA
stanscoyote: MFJ-1910 -- 33' fiberglass telescopic pole. Other manufacturers produce similar poles. One such alternative is the Jackite. 73 and Happy New Year!
D. Webster: What is the MFJ item number? I can't find it on their product listing.
dback4430: Dont even get me started about cw , Im getting there :) . I am experimenting , trust me , neighbor is thinking im nuts
stanscoyote: Oh Gosh, don't give up. There are all kinds of solutions for those of us living with antenna restrictions. I've earned QRP DXCC and QRP WAC with indoor antennas and five watts. Just makes it more fun. The secret: CW and perseverance. Welcome to Ham Radio. Keep reading but start experimenting. Sooner or later it will begin to make sense. 73, Stan
dback4430: Thanks so much . Finally a " direct answer " I am a new ham , have yet to make my first qso . Been playing with all sorts of antennas since i am in a second floor apt , The situation is grim. This may prove to be the best solution for me . I will just operate portable :) I have read so much on the subject that it all os a blurr . Thanks again
stanscoyote: Oops! I meant to say, "an end fed HALF WAVE antenna has a very high feedpoint impedance..."
stanscoyote: An end fed antenna has a very high feedpoint impedance which translates into a very low ground return requirement. You should read up on the subject (the Web has lots of good info as do the various ARRL handbooks). The shield on the coax feedline is providing enough of a "counterpoise" in my setup. If you feel better, cut a 1/4 wave piece of wire for the band or bands of interest and toss in on the ground. I'll bet you won't notice any difference. I didn't ;-)
dback4430: Thanks for the video . Why no counterpoise ? or am I missing them ?
MrXSpeaks: Thanks for this video. I now have a setup like this that I use portable
stanscoyote: It is an Elecraft K2 transceiver.
John Wojciechowski: I have the same UNUN from EARC in Hawaii. I bought 2 of them and keeping one as a backup. Great little matching unit. I live in a townhouse with a wooden deck and I run the endfed wire under the deck railing. Nobody's the wiser. Thanks for video.
stanscoyote: I am not familiar with the Ultimax 100. As far as the toroid power, it's good for 100 watts. Antenna is supposed to work in horizontal and sloping configuration, as well as inverted "L", but I've never tried it and am would not be equipped to measure differences in performance anyway. I use it purely as a "tiny footprint, no radial, easy-up-easy-down" vertical for portable and home 'stealth' use. Thanks and 73, Stan.
reddog694uk: This is very similar to the ultimax 100 antenna but a homebrew version, yes? Nice job, would like to see how it performs in horizontal and sloping configuration, also, what kind of power is the toroid rated at? Great vid !!
1903A3shooter: Roger that. W4GSM
stanscoyote: I guess you did not read *all* the comments and answers here, my friend - of course it is resonant *only* at a single half wave frequency where it's efficiency is maximized, but it's *also* darn good at *all* frequencies that are higher than halfwave. It's all about available options when we can't have the "perfect solution". High SWR antennas actually work quite well when properly "managed" - for example, the L.B. Cebik-style 44' multiband doublet that is non resonant in *any* ham band. 73.
1903A3shooter: I dont see the excitement here. A piece of wire with a 9to1 transformer. Your tuner in the transmitter is giving the low SWR reading not that wire. A end fed half wave can be a good antenna no doubt but it can not resonate on a bunch of bands like that.
radiosification: That's pretty amazing
stanscoyote: I own the 20M and 12M Par EndFedz and I love them also! They are for single band or specific bands. This contraption in this video allows me to work *all* bands from 40 through 6 with just the one antenna. It's all about options; it's nice to have options. 73 and good DX to you.
steveinkentucky: Oops...make that 10/20/40m...
steveinkentucky: I didn't make my end fed antenna, but I have 2 Par EndFedz--a full length 20m model, and the 10/30/40 QRP Mark II model. I love the performance, solid construction and amazing customer service that LnR Precision gives you. While Dale Parfitt no longer owns that section of his company (Par Electronics), Dale is always willing to discuss them and give advice. But, making some sounds like a good investment also.
Seymour Lindt: Awesome...ZS1CPT
stanscoyote: Thanks for your comment, Barry, and glad to hear of your success. These EFHWAs certainly deserve their rightful place among our many antenna options. They are efficient, effective, inexpensive, and able to be cobbled together by just about anyone. 73 es gud DX.
Barry Clayton: I made this antenna with a 10m fish pole and an 9.1 Balun I have worked USA on 10 15 12 also 40 and 80m, i said to my ham teacher should i be able to do this ? he said if you kicking out RF Ya hihi Barry 2E0PEC 73 QTH Halifax Yorkshire UK
pasqual dijkstra: i really like this radio, where can i buy it ?
