I use the 1979 at my QTH. Works great 20-10 meters!

>> The ARRL On the Air magazine Sept 2021 edition page 22 has a project to create a portable vertical antenna using the MFJ-1979. 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.

>> 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.

>> Hello all,
>> I am working on setting up a temporary HF antenna that I can setup or take down when not in use. 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.
