Ape shares a lot of good information in this presentation. A must watch for new and seasoned hams!
Thanks man, had a good time at the meeting 👍
Walt is legend! :)
Enjoyed your presentation…..tnx ! 73’ s de N4KGY
Nice to see Walt on other channels. Truly an inspiration.
Thanks for posting this John. Walt’s enthusiasm inspired me to reactivate after being off air since 1996!
That's awesome to hear!
John! Wow. What a great presentation. I have a Cushcraft 40 m Dipole. Will try a phased array from each half. I also have an old Butternut. Could add a 3rd element using the MFJ antenna SWR box to tune each element. Aim it at Europe from 1070 feet here in Roswell, GA. Sounds like a fun project. Thank you.
Amazing job to the whole team!!!
What a fantastic experience for all the students at Pleasant Knoll Middle School. A lot went into making this possible, We are all very proud of everyone connected to this lifetime memory. This is rigtht up there with the moon landing and Neil Armstrong's first steps on the lunar surface. I was among the thousands who saw it Live in Central Park NYC on a giant screen. A memory for life like this. Huge kudos to all who had a hand in making it happen!
Great video and Radio Club. Thanks Phillip
Great job, YCARS, ARISS, and Pleasant Knoll middle school
Really Amazing 🤩 very proud of my teacher kiddo there 🤩
Nicely done! Impressive organization and coordination. Looks like the kids had a great time! Thank you all for doing this and sharing it here.
Thanks, very instructive! One question though @1:02:50 "despite it's name it [a tuner] does not actually tune the antenna": doesn't the whole antenna system (coax + antenna) get tuned however? If yes, and you have choke at the input end of the antenna, isn't that the equivalent of tuning the antenna?
No the antenna tuner is a misnomer. It is a matching network. If used at the radio it only provides a combination or capacitance and induction to get the antenna system close yo 50ohms. It does nothing to the inherent impedance of the antenna system. So the standing wave (SWR) is still there between the tuner and the antenna. A tuner used at the antenna moves the mismatch further away from the radio and minimizes the coax losses.
Call yourself a ham with that audio lol
The best introduction to mmana-gal I have seen so far. Surprising that there aren't more views!
The spot on the wire also won't move for "Beginning of the Wire".
I failed to add, that MMANA won't allow the red dot to move to the end of the wire when I select "End of Wire"
I am just starting to use MMANA, and when I select source for a 20M vertical antenna, the program is telling me that selecting "End of Wire" is not recommended, and antenna performance values for SWR are nowhere near what I have measured for the antenna. Would you be able to suggest what I am doing wrong in the MMANA? I downloaded the latest version on 12/9/23. Thanks!
Im having trouble with the source as well.. Its like i have shorted coax all the time....
If your analyzing a 1/4 wave dipole, try lifting it about 10mm above the ground plane.
Sorry if this is a stupid question but when he says you don't need a lightning arrester, does this mean you can just stick it on any old pole or roof mount, run the coax to your radio and you're just done? No worries about disconnecting the antenna if a storm comes through and you're not at home? Is he just talking about the antenna and it's still a good idea to ground the pole or mount itself especially if connected to the house, or is none of it necessary?
Thinking about playing with this at home and in the adventure truck. I have a lot to learn now. Thank you

Great presentation! Thanks, Craig!
Thank you for providing a clear summary of NVIS. You mentioned a SOTA mast that you use. What do you recommend for ultralight backpacking SOTA operations. Is it practical to rely upon SOTA for wilderness protocol emergency communications? 73 de KLØT
You can use NVIS in emergency situations, and the Sota Beam mast I am using is not ultra light but light enoung i carry it in my pack. It is the Tactical 700 HD by Sota Beams.
thank you so much Callum it was wonderful to have you be the honored speaker at our club!!!!
You say between 0.1 and 0.25. then show a nvis antenna for 40m and 80m that is on a 15 feet mast.. 0.1*80m is 8m. So you need a 26 feet mast right?
Michael, if you run a 26ft mast the 40 meter take off angle is increased, it is a trade off you get a smaller radius of coverage on 80 meters due to the lower height and higher take off angle. as with all antennas that are multi-banded it is a compromise. But to your point you could run a 26 foot mast and it will work, just with a little larger skip zone on 40. Hope the video was helpful.
@@FromthehamshackwithNJ4Z thanks John. I've seen some very low to the ground dipoles. Ie 4 ft of the ground using plastic electric fence posts. I'm thinking these can't actually work that well because of the ground loss. Some have reflector wires on the ground under the antenna. I think below 0.1 and the variability of the ground conductivity leads to major differences in antenna performance. Anyway this video on the subject was great. VK6MIK.
Much excellent antenna theory and practical hints at the beginning. Using MMANA-GAL begins at 16:00.
Thanks glad you found the video informative. we are here if you have questions.

Great video guys very informative .
No audio????
Awesome. Ready for Part 2.
Good work here, looking forward to the rest of the series.
Thanks Andy!!!!
I know I'm a year late getting to these videos but..Nicely done. Very good job explaining MMANA. This is one I'll watch a few times for sure
Good presentation. I enjoyed it.
Thanks Joseph... Glad you did!!!
I have a Carrie Underwood version gold PR-35 - a gorgeous mic!! It and my generic PR-35 are loved by the live musicians I experience - but they are too cheap to get off their Shure SM-58s. I run my PR-35s thru a Symetrix 528 and switch around output to my Flex 6300 and KWM-2, and podcast/video cast PC.
Given we're restricted to on-air signal bandwidth, and acknowledged voice intelligence hearing, we have little, no need for audio above 3KHz, certainly 4 KHz.
Bob has some ah-mazing tales about audio. Listening was the first thing I self-determined in high school and civic theater - walk the audience floor... pissed off the local audio/PA contract company that I meddled with our stage PA system... ;) Well known - human hearing is sensitive to at best 6dB differences. Meanwhile - why is it many podcasters, professionals especially, continue to express such prevalent, no information, low-end 'thump'/pump in their voice audio? Look at their podcast spectral presentation and on-air spectrum presentation... hmmm. AM/SSB are not the only modes that low-pass, high-pass, pre-emphasis/de-emphasis and facilitating tone encoding/decoding, and how noise-squelch works are equally important.
This was great. I learned a lot.
EFFECTIVELY
Very sorry about the audio it was not in the presentation room it was in the transition from our location to youtube we are trying to see if we can clean it up
audio is terrible. I quit listening
Is there any way to enhance the audio?
Really outstanding video. I was just starting to develop a similar project and your video will help me greatly.
Glad we could be of assistance! Good luck with the project and let us know how it turns out.
Hi Thanks for the information ~~ Please can you tell me when placing x amount of Radials say 32 for the 10.25m Vertical ... where do you see the Length of each Radial within MMANA-GAL ? 73 M7AQP
Chili the length of the radial is not overly important, but I tend to use 10m or 5m radials. I would plan on a maximum of 4 wavelengths for the lowest band you want to use... so say 40meters you would want 16 x10m or 32 x5M ... and a minimum of 2 wavelengths in the case of 40 meters 8X10m or 16X5m... hope this helps. In MMANA the length of the radials is assumed to be 1/4 wave of the frequency. it is not documented well but that is what the software uses as the default length.
@@YorkCountyAmateurRadioSociety Thanks for the info .. you have given me the correct information, so I very much appreciate your time in replying. I have now built a few Antenna to realize the importance of Gain. And I am drifting steadily down that Rabbit hole to improve on all aspects in the making of any future project as you can understand. MMANA-GAL is great for designing with dBi Gain being the goal after size/cost considerations, and real construction & testing counts for much Vs Loss or predictive assumptions. I noticed wire diameter made hardly any difference with radial calculation, which saved me a few bucks this week where I will now increase the Radial amount by 2 more wavelengths. Last night at 2am I was getting 4000+ miles from UK to Florida with 3 Wavelengths & lots of tasty QRM .. So next test is to see if 4 Wavelengths really does allow for better Tx/Rx . MMANA-G indicates more Radials = +Gain = + dBi !! . Discovered my old Compass has been given a new lease of life along with HRD ROTATOR, giving me the exact direction of my Antenna Lobes .. 73 M7AQP
Great Op! 73, Marco IK2CHZ - K2CHZ
