I have gotten to the point (my FIL has my camera, so I cannot take any pics of what I have, but I will post in the future) where I am down to just needing to settle on an internal battery and then the deployable antenna. I am not looking for portable, as this ecom is for after a hurricane at the QTH. I need something which I can set up in the backyard and find out what is going on. NVIS would probably be ideal, but I do not have the room for the length needed for a decent one. I saw this: https://amateurradiostore.com/all-alpha-antennas-c-2/1080-meter-ezmilitary-sr-with-swr-251-p-181?zenid=gjuhgm6ml29p4orbouvi70ehp3 Seems to be an interesting and this: https://amateurradiostore.com/all-alpha-antennas-c-2/680-meter-vertical-with-tripod-mast-mount-field-bag-p-161?zenid=m54ek6qvecilacq9hba330n4d2 And they seem to fit the bill. They break down to a storable bad, and both have great reviews on e-ham (the complete one with tripod has only one negative out of 29 reviews). I would consider extending the height in some way, but I just wondered if anyone has tried these. Seem to be a lot easier (KISS after a disaster) than a buddie stick or pole. |

Quoted: There is a local ham that is using one of the 80-6 Meter Vertical antennas you linked, but his results have been less than stellar. I would imagine that a fiberglass vertical and a few radials might do just as well for a bit less cost. I know there is no magical antenna, but I keep hoping there might be!  |

Personally, I use one of the Jackite fiberglass poles with a piece of wire on it. I feed it with 6+1 copper fishing line out of a coleman clothesline spool. It works well for NVIS if I make it horizontal-ish, and it actually works DX with a vertical.
If you want a ready-made solution for NVIS, those aren't bad, a local guy has one on his deck as a HOA-friendly station antenna. He has about 100ft of copper wire zig-zagging under his deck planks to make a ground plane. |

Something to seriously think about is an end fed antenna like this.
http://www.ultimax-antennas.com/services.html While this is not a log periodic it is serving me quite well on 6 meters through 40. I've made many contacts with mine, logged 185 qso's. On 20 meters have contacts from 3 miles to over 7700 miles. (the guy that is 3 miles from me is a friend, and talk to him several times a week on 2 meters. I have him in my log on both 6 meters voice and 20 meters digital. Both long and short 20m contacts were on about 30% power digital, approx 30 watts. 6 meter voice I can work him from 100 watts down to 10.) The box is double gang size and the wire coils up easily. Deployed the wire is 24' long. I've ran mine in sloped and horizontal and deploys quickly. I have deployed it across some low hanging branches down at my camper at the rivers edge and made a few contacts. I'm planning on doing field day at my camper this year using it but will get the antenna a bit higher. So in conclusion I'm quite happy with my antenna and with some rope, sling shot, fishing line and a sinker I am confident that I can be set up and on the air in short order. edit spellin |

I have been using this with good results in a sloper config. http://chameleonantenna.com/BASE%20ANTENNA/CHA%20EMCOMM%20II/CHA%20EMCOMM%20II.html |

The Amateur Radio Store are producing a lot of junk believe me!! I saw what they're doing and it's a very pale imitation of what Chameleon Antenna are producing!! They're building their antennas with toilette PVC "T" fitting and they sell that like if it was a high end antenna. From what I've learn about them is that they're trying to imitate what Chameleon Antenna are doing but on the cheap and poor end of the manufacturing spectrum. If you want quality then I'll recommend you to have a look at the following product which seems to be a brand NEW product:
CHA HYBRID-MICRO The guy in the video pulls the antenna from his pocket! From what I know about those antennas is that they're really well made and performant. Everything they do are made in the USA by professionals. Anyway!! SGO |

Also if you go on their Facebook page you'll see what they're doing: www.facebook.com/CHAMELEON.WALKER
They seem to have some serious production skills: https://www.facebook.com/photo.php?fbid=302015973294760&set=a.131335017029524.30148.100004590791774&type=1&theater Their shop looks AWESOME!! http://www.facebook.com/photo.php?fbid=292498390913185&set=a.131335017029524.30148.100004590791774&type=1&theater I can see myself using one of the machine to work on my rifles with a form 1... |

The second antenna is little different from the Buddipole vertical setup. The first one is just ludicrous, the only way their description makes sense is if it's just a dummy load you attach a wire to.
A vertical is the last thing you want if you want short range/local HF. How much space do you have available? Pretty sure we can come up with some actually functional antenna for less money. You've got to be kidding me. An SO239 to wire adapter and 60 feet of wire, for $230. |

SGO Are you Carl Lavoie ( http://website.informer.com/Carl+Lavoie+Chameleon+Antenna.html ) "[email protected]" or do you shill for him? The reason I ask is because it seems like your posts are pretty much only dedicated towards directing traffic to Chameleon, and come across as pretty corny commercials. Your writing style seems similar to his in some ways as well. http://www.ar15.com/forums/t_10_22/674433_Dipole_building_question.html&page=1#i11532352 http://www.ar15.com/forums/t_10_22/674419_such_thing_as_a_2_1_balun_.html&page=1#i11532351 Report sent to mods. |

How much space do you have available? Pretty sure we can come up with some actually functional antenna for less money. My back yard is about 50' by 40', with some palm trees; however, smack in the center is a 25' pole for my OCFD, with some guy wires, so it is a bit tight to be able to set something else up (and avoid the guy wires). I figure after a hurricane, even if I bring the pole down to it collapsed height of 8' or so, it will be toast. So I am looking for something I can store in the house, and then throw up afterwards. I believe I will make my own matchbox end fed, and give it a try. |

After some feedback on my man pack antenna I found this antenna.
http://www.airtronix.com/pv-7/ If there are trees around I have had good luck with a 9:1 unun and 31' of wire. But I like self contained systems better. |

On the snake oil remark, whenever I see an antenna that's supposed to work "with a non-resonant length of wire" and supposedly works "on all bands" AND has a sealed case, I immediately know it's a dummy load.
There's a pretty widely used mobile antenna that includes a non-inductive resistor in the "matching section" in the base. |

Are you tied to the company in any way (This is includes friends with the owner)? |

I understand the ease of Hawaii EARC end fed antenna; however, it is my understanding that the majority of the RF is going to be at the fed point of the antenna (at least with a dipole), so while it is easier to have the fed end near ground level (less coax), wouldn't you benefit from getting the fed end up in the air and having the other end near the ground if coax was not a problem? |

Maximum RF is at the high current node(s) of the antenna. High current nodes are at odd quarter wavelengths away from the end of the antenna. |
