",,,anyway the dimensions of your antenna (ch41-ch49) are not suitable for your Tv channels...!!! ,,, why do not you want to try a kind of this antenna ... ??
-
,,, which TV channels are you working on...!!! ,,, simulation of specific program antennas can never fail...!!!
-
,,, okay,I will try to do this for you but give me the dimentions of this antenna...!!! ,,,for GSM / LTE 1800MHz antenna must cover these frequency domains; UL = 1710-1785 MHz DL = 1805-1880 MHz ,,, so the panel antenna must be broad band BW = 170 MHz min
-
,,,for your antenna about these are the results ... ??? ,,, the frequency band does not match and the impedance is not good...!!! ,,,also, the gain in directivity is small...!!!
-
,,,for which antenna ... ??? ,,,can it be solved with this type of reflector ... ??
-
-
,,, it can also be done ...
-
And it goes better than the gnutik...???? ,,,yes, it's a good antenna...
-
,,, it does not matter, I would like to know the gain of the antenna ... !!!
-
,,, if you want, I can make a simulation for this antenna ... !!!
-
,,, the excellent realization ...!!1 ,,,on which channels did you built this antenna...???
-
,,,more than that, I think can not...!!!
-
,,, and this is perfect ...BW=650MHz-925MHz
-
,,,so this HDTV antenna(650-800MHz) has only one support ... !!! It's for my friend Garry...!!!
-
,,,or you may want something like that....http://www.lan23.ru/forum/showthread.php?t=8107

-
I do not understand what you actually want ... you have to decide .. !!!!
-
,,,see this...
-
"Anyway, you have to know that such an antenna does not have a good isolation between the ports (P1, P2)...!!!1
-
,,,,why do not you try to adapt the old antenna by doubling it ...???!!! But it's usually like that...
-
"if I said 15dBi, then let it be ...!!!

,,,okay,this it"s... Kharchenko antenna for 4g modem with your own hands Called the device by name of the engineer who first came up with it. It is a powerful external antenna for usb modem 4g made with his own hands, the schema for the required option can be found in the Internet. We present the easiest. All the parameters are calculated depending on the frequency of reception and transmission of the modem. ll the parameters are calculated depending on the frequency of reception and transmission of the modem. The calculator can be found here. http://www.texnic.ru/tools/gl/gl002-1-1.html "Soon I will give the calculated dimensions for double-biquad 1800MHz, with the side of about (0.375 ,,,,0,55)* lambda...!!!
-
Yes, it's real this gain in directivity...!! "But it can be so ...
-
"No, you do not have to buy an SMA, just unzip the plastic case from the antenna SMA...!!
