The Chameleon CHA SS17 is almost identical to the MFJ-1979 – https://chameleonantenna.com/shop-here/ols/products/cha-ss17
Some youtubers are saying the top portion of the chameleon is stiffer than the MFJ… which is important if you try to take two of these and make a rotatable dipole. There are a number of youtubes out there showing both of these in various resonant configurations with and without base coils such as the Wolf River Coils or the Chameleon coils. 73, Mike KK5SC From: BVARC <bvarc-boun...@bvarc.org> On Behalf Of Venkata Appala via BVARC Sent: Sunday, August 6, 2023 9:54 PM To: Shannon Tassin <stas...@hotmail.com> Cc: Venkata Appala <pradhan...@gmail.com>; BRAZOS VALLEY AMATEUR RADIO CLUB <bvarc@bvarc.org> Subject: Re: [BVARC] HF antenna and coax Thank you Shannon.

If you are an ARRL member, you can use the ARRL mags app to find it. It has a mount and everything else needed. I’ve made this project and tried it out and it works quite well. The article has you mark the antenna for the right spot for each frequency, but if you have a tuner in your setup, you can extend it all the way, tune it, and it will work well without the manual adjusting. I have a backpack and a PVC tube I use to make it all portable. I made some tweaks to the project including a round plate to attach the radials. We have some coax experts in the group and so I am sure they can give you more information, but keep in mind for HF, you don’t need as high of quality coax as for VHF/UHF. Happy to give you more details – send me an email.

For this, I am exploring MFJ 1979 telescope antenna. I am not sure if this is the right choice yet. My idea was to use some mount(yet to figure this out) in the backyard, run the cable inside the home when I want to use HF. In addition, when I am visiting some park, planning to mount if using some mag mount. I don’t have much of a backyard and wanted to see if this antenna can be used at home and when I am visiting places. With this info, I have few questions. Please bear with me as I am absolutely new to Ham and might ask dumb questions. While reading, one thing I realized is that, the antenna depends on the bands I wish to use. Well, at the moment, I want to start with something that can get me on air for commonly used frequencies where I can listen in and learn how to use the radio. At the moment, all I have is a HF transceiver with builtin tuner. 1) Is 1979 a good antenna? It appears it is around $70 and I am assuming this can get me started without breaking any bank. 2) Coax…looking at the options, this seems like a candy store and I can’t figure out which one. I am guessing something around 50 ft in length might work and my limited research shows LMR 240 might be good option. Is this true or should I find a better alternative? 3) Any suggestions on mounts for the antenna that I can use in the backyard? Ps: Thank you to Ed and Richard for pointing me in the right direction at Fulshear farmer’s market. I am also researching on end fed antenna but this will be a build/diy project. Thank you for all the guidance and suggestions. 73 Venkata Appala KJ5BVS pradhan...@gmail.com<mailto:pradhan...@gmail.com>
