Bump!

Bump!

Thanks to make me discover that sparkplug-antenna !! HI
excellent !!

Hi Mark,
thanks for sharing that info. I'm in the "balun/transformer subject" for now and not heard of that method.
Interesting measure's results !

73, Ben

Hi Gil and all members. Greetings from Arizona. Thank you, Gil, for doing what needed to be done, creating community. We have our societies in various countries, but real community is hard to find. It is especially critical now, as there are signs that we are all soon to live in a world torn apart by war. In any kind of such crisis, Ham radio has been vital for the preservation of community, and even for the functioning of society. I was involved years ago in disaster relief, mostly in Central America (Nicaragua and Guatemala) where earthquakes devastated large areas and the basic infrastructure of the society was impaired or destroyed. I was part of a relief team from the USA and we could only communicate with our HQ in the US by using local Ham operators. It was that experience that inspired me to become a Ham. So your group here is especially meaningful to me, as I believe we may be forced to rely on radio for basic communications. Thank you also for the videos on the 49:1 EFHW antennas. I just received a toroid and will build one. Perhaps we meet on the air using them.

Here is a image of a double bazooka antenna calculation.

With it being 3 feet in length it is a decent antenna for using on SSB on VHF 2M. Along with the 50 Ohm cable it is light enough to roll up into a backpack and carry.

Here is the link for the antenna calculation from  West Mountain Radio.

Could be a fun project as a suspended vertical from a tree or between 2 trees for SSB use. 100 watts and a wire did a build on making this with tips on how to make one for HF use.

Youtube link to 100 watts and a wire.

If you get to build one for VHF or HF let me know compared to a normal dipole from tests. Could be some fun for H/T in a pinch.

Hello. Has anyone tried the KN5L transformer winding ? Came across this design when researching end fed transformers.

Yaesu FT-817ND.  I own a few radios but the 817 is my Baby.  I bought it for the all modes all bands features.  I have talked to multiple continents and love using it.  I just ordered a 1296 mhz transverse to use with it.  It is just a handy radio to have.
