Awesome practical antenna demonstration 🥰

Nice bracket but they do not ship to Canada :(

How did you attach the mobile radio head to the camera mount? Did you drill a compatible hole into the radio head?

What’s the name of that grounding clamp with wire ? Where can I get one ? Thanks .. 73 from Costa Rica

So is the first setup the sloped wire configuration? I always thought the antenna would be in the trees and the line winder on the ground, I think I did my emcomm wrong .

Nice video. Folks may consider a DIY battery. I just built a 105 AH LiFePO4 battery. The 4 prismatic cells just nicely fit in a U1 battery box. I used a JBD-SP04S020 4S 120A LiFePO4 BMS which has low temperature cut off and is controlled via Bluetooth app. I had the BMS left over from a previous 560AH battery build for my sailboat, but new would cost $60. Alternatively, one could get a basic BMS for about $12. In the end, the 105AH battery cost me $115 for the cells plus $12 for a NOCO U1 battery box. Looks and works great. I can send phots if interested.

Surprised to see you doing this test at night. NVIS typically work better during the day. There may be more noise, but the SNR is still better. Very interesting. 73

It looks like a very good battery, I will buy it now😀

I have their 50ah and their 20ah battery. Bench tested them both in the bench and it exceeds their advertised stats. 100% will buy again!

Nice review Kevin, I have one coming soon and will do a similar test.

That’s a neat battery. Would probably last a decade running a QRP rig!😅 nice review as always Kevin.

Not a bad price for the battery, really like it, thanks for sharing

For the reason I have not in off time a G5RV at 15 ft from ground and 2x20m long with twin lead of around 10m long + air Balun 4/1 ... I'm quite happy with it.. of course all homemade 😊

Is S&K still making these? It is listed as sold out, and they have one item for sale on their website. This is a great video, though, and this antenna is exactly what I'm looking for. 73 de Greg K8LAM

This looks like a great product! But they don't make anything to fit my old truck.

Would 50Ah of run time be enough capacity for your needs? Check this one out. www.amazon.com/dp/B0CPJ1B5NR?ref=myi_title_dp&th=1 www.vatrerpower.com/products/vatrer-12v-50ah-lifepo4-deep-cycle-battery Get 5% off with this code 7HN4JLZ7

Ok I just ordered one for my wife's Tacoma. I'll get the truck as a handme down in year or so. I hope we keep the truck. It's been a lemon so far.

I need one. I just made one with a pocket sling shot

Thanks nice little set up !!! great information!!!!😀

Interesting video, finding hardware for me changed when I discovered RAM MOUNTS which are an USA based company I believe and I would say the mounts you have shown are similar. So for example the 480 head unit I felt you over complicated the fact you had to fabricate the l bracket when ram mount do several brackets that could be used to fit and are all adjustable as I also have the 480 head mounted in my car. Ram Mounts do the track system, they do systems that fit on the chair bolts and can support laptops and radio equipment. Anyways I hope you don't take offense at my comment, I am sure you know all about RAM MOUNTS. 73 Duncan

Looks awesome but as usual another manufacturer that doesn’t support Nissan

So is this an EFHW or EFRW?

I'd not seen this system before. Nice intro. I'll be shopping :)

This is one of the best mounts systems I have used in a vehicle, Would this type of mount work for your radio needs?

Thanks Kevin. Looks like I'll be getting two Redodo's at 200 ah and 200 amps. Coupled with 800 watts of solar and a 3000 watt inverter/solar charger. It'll be a good setup. 400 ah with a full sun recharge of around 30 amps (derated). This should leave me with a full charge after daytime activities at full draw. Your thoughts? Anyone's thoughts?

Did I miss the SWR readings in the elevated TDL configuration? Ok it's at 12:12 That's why I'm re-watching. What's your thoughts? Which performs more gooderestest? < Don't judge me because I'm smart enough to make up new wirds🤣 CHA TDL or LEFS 4010

Is that Chuck?

I once did the math on these. Basically, what I remember is that you get 10% or less efficiency on 40m, about 20% on 20m, and 50% or maybe a bit more on 10m. You get about 2-3 db of gain in the plain. I’ve had success with them. At the last solar maximum, I made a contact in turkey. You’re probably radiating 5w on 20m. Not horrible. Is it worth $300? Probably not.

Curious how two station 25 mi!es apart can have one in daylight and one in the dark?

Great video! de W2CSI

I have seen a demonstration where a longwire laid across the ground can power a sequence of LEDs from RF coming from a local AM broadcast antenna and a gap attached to a metal fence post produced a spark.

250 dollars !! Just 1 balun 9/1 and wire !! No!!! Expensive .. so…

Thanks for the walk through - bought a used KX2 two years ago and have been meaning to do this, and it was super easy. Did it on my Mac with no issues at all. Focusing on the KX2 this year and making it my primary transceiver. Thanks!

Great comparison and versatility. Quick setup.

Superb video. Informative and inspirational. Thank you.

Isn't a dipole directional if it is in free space at least a half wavelength off the ground?

Yes Denis replied to my email right away. Only if he has a version for allstarlink..

Thank you very nice KD2MPI in New York

You are correct they are for any aircraft so they will be able to spot the wires that are hard to see. I’m an old Army Helicopter Crew Chief with 20 years of flying. One of the early things we were thought due to flying lots of low leave flights from 500’ to 50’.

Those primary loops could become better by crushing them into an oval, affording more area to couple,, You are welcome Chameleon.. KK5VN

Nice job, 73s from U.A.E.

Great reports..I think this is the antenna I need..or at least some brand of Loop Antenna. Thank you so much. Love your channel.

Awesome video-thanks again! Curious-could I use something like an Ed Fong or maybe a Hamstick clamped to this mast?

Great stuff. Thanks

Great build.. Thank You

Hi K7SW, I was wondering if you're on the 8th floor of the building , do you still need to pull the length on the antenna, or would it work coiled up?

Very easy to follow. Your voice is easy to listen to.

Know nothing about ham radio but my grandson is into ham will this antenna work on 10 meter? Would like to get it for him as a gift

Hung a wire antenna up for my Dad yesterday. While holding my slingshot, I was thinking man I’m building a launcher before doing this again. 73’s
