- VAS 5.8Ghz SkyHammer SMA Antenna - True long-range Omni-directional antenna! Sky Hammer utilizes a pair of high-performance Minion Pro antennas precisely phased and impedance matched to achieve 5.25dbic of gain and 360 degrees of coverage.
Long-range and 360 degrees of coverage in one, the VAS 5.8Ghz SkyHammer SMA Antenna is a true long-range Omni-directional antenna! Designed by IBCrazy, the VAS 5.8Ghz SkyHammer SMA Antenna utilizes a pair of high-performance Minion Pro antennas precisely phased and impedance matched to achieve 5.25dbic of gain and 360 degrees of coverage. The stacking and phasing take the unused vertical coverage of a single antenna and pushes it outward along the horizon right where you need it. While typically considered to be a receiver antenna, the VAS 5.8Ghz SkyHammer SMA Antenna can be mounted on a long-range quad for exploring places where other antennas simply cannot reach. When using the VAS 5.8Ghz SkyHammer SMA Antenna on a VTX be sure to watch bank angles or you could point the null of the antenna directly at your receiver causing loss of signal.

**************************************NOTES*******************************
Remember, these are really Panel antennas with wide range horizontally but 20 degree focus area.
they may be shaped like omni's but treat them like 360 degree panel antennas and you'll be fine!
******************************************************************************
VAS ION:
The VAS Ion V2 is a true upgrade from its predecessor, with an increased axial ratio allowing for much better rejection of oppositely polarized signals.
The VAS Ion V2 sacrifices no performance from the original version of the Ion but is over 1.5g lighter and 20% smaller. The VAS Ion V2 is a true upgrade from its predecessor, with an increased axial ratio allowing for much better rejection of oppositely polarized signals. We also addressed the large null from the original design, closing it up considerably. The VAS Ion V2 is a must-have for any serious long-range pilot.
Gain: 2.5dbic
Axial Ratio: .94 (Measured)
Polarization: Right Hand Circular (RHCP)
Weight: 7.4g (0.26oz)
Antenna Connector: SMA

Man, I had to laugh... Great intro!
Hi Alex, sorry i didnt fully understand their use, great antenna tho as always!!
@@MindOfBoomBoom - That's ok. You had me laughing for the first few minutes anyway ;)
@@CAGreve1231 I'm going to be running two of these both in proper vertical orientation on my clearview pro, what do you think about this setup?
@@hansyolo9163 - That would work well.
@@CAGreve1231 hi vas, whats best antenna mushroom or skyhammer ? i wanna buy vas omni antenna for combine with my vas box pepper extreme, thanks
I think in the world of analog FPV, there will always be breakup and intermittent loss of signals, bound to the limits of what we can strap to our head and fly on these little quads, no matter how much power you're blasting and how well your antennas are tuned.. this is because of circumstances we cannot control; environment, multipath, temperature inversion, attenuation from structures or trees.. etc. In my opinion there are a lot of great Rx/Tx antennas out there already, but to make a better one tomorrow, or next week, or next year, will not move us any further than we are now, or ever provide us with 100% perfect reception throughout the flight.
The doc brown goggles! 😂 they are legendary.
But Sadly soon to be retired once the Orqas get here!! see ya next weekend at Nationals?
Alex Greve is the man behind the Hammer. I've not been able to test his Hammer just yet. But, I have the Minion antennas on all my Rigs. Great man and best antennas on the market. Outstanding video reception for above the rest!
yeah i meant to say that. No Doubt these are great antennas if you go into knowing they act more like panels it appears from the graph information unlike IONs that are full coverage. Alex always makes great antennas, i just didnt fully understand what i was buying and this video is to make sure people know more than i did when i bought them. thanks for correcting me.
Was checking these out but got a good laugh out of it vid thanks man
hahahaha thank you!! not bad antennas i just thought they worked differently! thanks for watching!
I really couldn't tell the deference i have some coming and ill see thanks
i dont believe i used these properly, i am sure VAS can tell you the proper orientation for these to get the best results!
very helpful. thank you.
Would be great to see a real max range test. Like how far can they go and then compared to let's say a crosshair or a Pepperbox
Entertaining. As you already know, you were just using them wrong. The way you had the one antenna oriented on your buddies goggles was more correct, and probably why he got good results. The thing is, we rarely fly high directly above us. Most antennas' "nulls" are still good enough for the perfect line of sight that you get when you fly over your head. So using these and pointing the disc at the horizon is quite effective. I have 4 of them on my DJI. I have them all in a vertical orientation. In my current testing, they are doing better than a VAS Cyclops.
Yeah sometimes ya just gotta touch the fire to see if it is really hot, hahahaha thanks for watching and explaining, i do appreciate it
Why are you using 4 of the same antenna? I would use one or two of them and then on the other side an even higher gain antenna.
@@skinnyflea2628 Why does the VAS Cyclops have 4 identical antennas in it? And why do folks use two sets of XAirs? It's because the system is MIMO, so can make use of all 4 antennas at once to compare signals and recreate data. What you are suggesting is turning the system into two separate modes with diversity between them. This does not give you the "best" of both worlds, but pretty good of both worlds. For the best of each world, you want 4 antennas that match that world. My standard world of flying uses more multi-pathing in all directions, so I run omni's. But when/if I fly longer distance in one direction, I will switch to my VAS Cyclops to get the best of that world.
@@rcrdps8144 That was a great explanation. Thanks man! Now that I think about it, It makes sense. I would imagine you get pretty good performance out of that set up.
@@skinnyflea2628 Actually,.. I "did" get great performance. However, I had been waiting for the TrueRC Singularity stubbies to come in stock because they are super short and convenient. I was expecting less performance than my SkyHammers, but thought they would do just fine for my everyday flying. Well I was pleasantly surprised that the Singularities beat the SkyHammers. So they are my daily drivers now.
Meh still not ditching my pagoda lol. Maybe one day...
I can see why the skyhammers wouldn’t work as well with rapidfire, since it’s supposed to blend the two signals together instead of being a diversity system. In other words, I’m not sure but it’s probably blending those nulls in with the display. Not sure though.
Did you do a range test on the sky hammer? That would be a good video since they are made for increased range.
@@gs550t81 SO SORRY you are right, i did respond to the wrong comment, lets start again!
i did not do too much of a range test. i mis understood the Skyhammers functional use. i thought they would not be so linear, but they are good directional antennas with a narrow beam.
This is NOT an intervention... we want you back in the circle of trust.
Oh thank god, its crowded outside the circle of trust!!!
About the same antennas!📶
Yes antennas!!
Dang sucide tower was there a few weeks back miss Florida already 😩
wow really? sorry i missed you!! hope you got some good footage!!
@@MindOfBoomBoom I did get some footage .. in the near future I'm moving down there ..
So the sky hammer would be better suited as an rx antenna, and use something wider on vtx?
That hammer into hahah
Try only one of them. Two antennas with same specs makes all kinds of problems.
well all this was over my head.....
But the pretty graphs are pretty!!!
@@MindOfBoomBoom Yes...Lol
What the hell is a panel? Are you talking about a patch antenna?
The amount of loss just from one of those SMA extension is more than you'd think and can change by a little bend as well them slowly getting worse and worse the amount of times they are bent.
I like VAS and use two Mad Mushroom V2 and two Pepperbox Extremes on my HDZero VRX and can penetrate through walls lol same setup I ran on Analog actually but still have more than a grand in just antennas even multiple rf meters...
**edit** also your testing is super flawed as you not only used two different VRX's but two different models of VRX's. You realize electronics generate RF noise and even two of the same type can generate different types of noise. So there is not one antenna thats a fit all better than everything else.
I've seen one of my 13.25dbic antenna get out performed by a $10 5dbic patch on someone else's VRX yet put it back on my VRX and it out performs their patch on on their VTX. Sadly even the same antennas can perform differently depending on age and time of manufacture.
10 dbi is weaker. 5 dbi is stronger. If you want to go further with clarity get DJI lol. I still like analog though.
not quite sure how DBI was explained to you? but thanks for watching
@@MindOfBoomBoom bwahahahaaaa
@@MindOfBoomBoom The irony is your 10dbi comment in the video is also wrong. By adding the 2nd skyhammer you just added another 5dbi but in a different direction. It was a good thought but the donut pattern is just squished too far so you get still get some drop out points. Probably best to just have one skyhammer installed vertically and then a vas minion pro (or ion) sticking straight out of the goggle. The minion has the good ratio with only a small null but that won't matter because the skyhammer will be the covering that up. Then when you are close and flying overheat the minion will have the best pickup and you don't need high gain at that point.
Lmao
