+Sasmita Dash do you also work in array processing ? me too.

what would you do to extend the wifi range between an AR drone 2 ( quad copter flying toy) that uses its own wifi to connect to an ipad for navigation control.? The drone range is about 160 ft.. It would be nice to fly it in about a mile or 2 range. Any ideas? it would need to be portable with the ipad. Thanks

hi, i want every one here to know that this company is "THE BEST" i have personally done business with them, and they are great. i highly recommend them for your wireless needs. ben...

SimpleWiFi commented on 09 Oct 2012

If you are referring to the distance the Yagi can grab a signal from,it is about 3 miles. Approximatley 4.82803 Kilometers.

SimpleWiFi commented on 23 Oct 2012

Expect up to about 1.6 kilometers.

Prasanta Karmakar commented on 11 Jan 2013

hey...what it's cost ????

Thanks for the love ben!

2 Meter Yagi Antenna w/ Gamma Match (Part 2/2)

Dave Tadlock commented on 03 Apr 2011

@bognapalm If I remember right it has something to do with the formula for calculating a series LC circuit. The formula is in my old advance class study guide but I'll have to search for the book. Some yagi antenna modeling software, many available for free download on the internet, will calculate the length of the gamma rod for you. As for this style of gamma match you could scale it down for the 70 cm band but it might be a bit long and unsightly if used on a lower band such as 10 meters.

Dave Tadlock commented on 12 Oct 2012

Normally all the elements are grounded to the boom when using a gamma match. An antenna with a dipole driven element uses an insulator to separate the two halves of the driven element and can be used to insulate it from a metal boom. Dipole fed antenna elements can be mounted on either a non-conductive boom or a metal boom using insulators. Hope this helps and thank you for watching! :)

the KiloMike commented on 11 Nov 2015

The adjustment of the gamma match was not addressed and it looks wierd all the way to the end. Flip it over if you want it vertical for FM. The mast does not need to be grounded, the elements work in relationship to each other. Want more elements ? Male them a little shorter or the same as the last director. Space about the same. Check online yagi calculators.

Dave Tadlock commented on 29 Mar 2012

It was fortunate that the holes that I reused were spaced 12-3/8" which is an optimal length on two meters. The TV elements have also been trimmed to the correct lengths and were calculated using yagi antenna modeling software. This old TV antenna has been completely turned into a terrific little 2 meter amateur radio antenna. ;)

Dave Tadlock commented on 01 Jan 2011

@JuggledaJungle The original antenna worked great receiving the FM broadcast band (105 MHz) when the TV antenna was new and fresh out of the box from Radio Shack. But the antenna, old and broken now, has found a new useful purpose by being converted to transmit and receive on Amateur Radio (ham radio) frequencies. ;)

Dave Tadlock commented on 17 Mar 2011

@virtualbush Yes, the adjustment may be a bit tight. To increase frequency I could have made the gamma tube a few millimeters longer. Sliding only the grounding strap inwards seems to lower the frequency. SWR will of course also change with height and vary depending on the coax cable length. Thanks and 73! :)

virtualbush commented on 17 Mar 2011

Perhaps some demonstration/information (A short Part 3?) regarding how to tune using the gamma in case the SWR is a bit higher than we might like. Enjoy! I will indicate that we would slide the tubing either in or out over the dielectric. Hopefully not inward in this case because your assembly is tight!

Dave Tadlock commented on 23 Jul 2012

No. The driven element is attached directly to the boom. More information about building this antenna is on my web site. The link to my web site is on my YouTube channel. Click my username, then click the Feed tab. The link is in the upper right corner of the page. 73 and thanks for watching! :)

Rob Lawrence commented on 03 Sep 2015

hi Dave,, ive just built this 2m yagi plus gamma match,, my first build ;) i enjoyed the build, thanks for the great videos,, im fairy new to 2m radio,, you say this antenna is horizontal for SSB so do you mean if i turn it vertical,, i can use it for FM ? cheers Rob

joee2047 commented on 22 Jul 2013

when you wrapped the copper part of the gamma match on the pin of the coax connector and than soldered it,,,, it was only to the center pin and not touching the side at all,,, is that correct,,, just so I know,,,, thanks!!!!

haassman commented on 03 Nov 2013

what is in the middle of your gamma (the white insulator....with copper). Can you not just use the element, or double aluminum elements up together? When do you have to use a type capacitor in line with the coax?

M0csi commented on 29 Jan 2011

Thanks for the information with regards to the Gamma Match ... pictures or in this case now video ... tell a thousand words ... I will use this feed system for 440mhz on the beams I make ... Thanks Mike ...

Dave Tadlock commented on 24 Mar 2011

@zx636racer Element spacing is mentioned in part one. I simply removed the plastic TV antenna insulators and used the same holes to mount the elements. The spacing is 12-3/8" between all elements.

Owen Baldwin commented on 12 Jan 2013

Dave, excellent videos on all your projects, very instructive and educational. Well done young man you are an inspiration to young amateur enthusiasts. All the best 73 ...Owen G0RCL

umajunkcollector commented on 17 Jun 2013

Looks as good as a Cushcrap. I like it, and think i'll try to emulate it for 2m ssb. Now all I need is an old TV antenner.

JuggledaJungle commented on 01 Jan 2011

what bout the frequency? it will transmit in 144 mhz?? how can you fix that to for example 105 mhz?

Dave Tadlock commented on 29 Jan 2011

@M0csi Glad you can use the info. Good luck with your antenna projects and have fun! :)

bognapalm commented on 03 Apr 2011

Is there a formula to calculate a gamma match for different frequencies?

Jackupnow commented on 06 Nov 2011

Hi would please do a video on a 6 or 10 element beam for 2 m

joe s commented on 17 Dec 2012

how would i build a 900mhz RF yagi antenna i love this stuff

honeybees1 commented on 23 Jul 2012

Is the driven element isolated from the rest of the antenna?

Dave Tadlock commented on 15 Mar 2011

@matthewz07 Have fun with your new antenna and good DX! :)

Djordje Marjanovic commented on 27 May 2013

Can I use this type of antenna for WiFi signal

Dave Tadlock commented on 27 Dec 2010

@808514 Thanks! I'm glad you enjoyed it. :)

JuggledaJungle commented on 01 Jan 2011

this can be used as an fm antenna??
