| Jan 29, 2018 at 8:22 | comment | added | voices | @Dimitri That's right. We used to tune our VHF antennas with a pair of sidecutters and a handheld RF signal analyzer. I did anticipate having to use a new or modified antenna; although the huge array of WiFi antenna shapes & sizes on the market, has left me kind of confused about the physics. But I'll continue to look into it and share the information. | |
| Jan 29, 2018 at 7:53 | comment | added | Dimitri | @tjt263 Ok. Now you have a problem then. You can't simply use the antena used for ITU-R in case of WIFI Frequencies. You should make check this foto for example: robkalmeijer.nl/techniek/electronica/radiotechniek/hambladen/…. As you can see different length for different Frequencies. I won't lie to you I have no idea if it would work if you modify the antena you have, but that could be a good experiment. Check in google "antena length calculate". You will see a few useful formulas. Hope this helps friend. | |

But I was actually referring to the 477MHz UHF Citizens Band used in Australia & New Zealand (476.4250 MHz - 477.4125 MHz; colloquially known simply as UHF). I thought this was a common standard throughout Europe & North America, but apparently not. | |

| Jan 26, 2018 at 12:21 | comment | added | Dimitri | In theory UHF works from 300Mhz to 3Ghz so it should work for lower F antennas. However you should check the bandwith. But if you can test it I would like to see the results. I find this post very interesting. As for the way it works is throug inductance. | |
