NEED HELP WITH ANTENNA SELECTION??

#1
Hello guys, i have been flying fpv for about a year now and want to get into long range. But I would first and for most like to get some ideas on which antennas to use. I would like a better antenna for both my 200mw 5.8Ghz system and for my FrSky 2.4Ghz Control system.

I came across this website and would like to get your opinions on these two antennas??

Watch this video.
What do you call long range? Some people find 2Km long range others 10Km. Also how much are you willing to spend? With the setup that you have it's hard to fly long range because it's short range equipment. Adding those high dbi anntennas wont work because it has a really small beam of reception. Just watch the video and tell a little bit more about what you want what you fly and stuff. Also your plane must be cabaple of flying more then a hour because it takes allot of time to fly for example 10Km.

Well fortunately I have watched that video three times now and understand it. I never fly FPV by myself as im not comfortable with it not having a spotter. So in that case having a narrow field of view is not a problem because my buddy will be my "antenna tracker". 15km is what my ultimate goal is. And im almost certain that it will be extremely hard for me to reach that with 5.8Ghz but it can be done. If you look at my other started threads you will see exactly what my ground station looks like and my airframe. I get about 30 max flight time with it cruising at about 35-40km/h.

Hi-
I don't do long range but know some stuff about it. Antenna tracking is almost a must unless you are really high or have a buddy. as for the antennas I don't know because I've never looked into stuff but I have seen more people use the second one type in more FPV vids than the first. Make sure you have a long enough antenna for your transmitter to because that will probably go out of range in a mile or two.(UHF system) maybe try searching long range FPV directional antenna on google or something. I remember going to a website that had a antenna that looked like the second one and it said the range was 150 miles which is way farther than your ultimate goal was anyway so you could always have locked in signal too. Good luck:)

Get annother battery with to double your flight time. Also the antennas that you linked are called yagi's but they are not usable for human tracking. I bet that your friend cant track you when you are 2Km away! You would have to use a yagi. 2.4 GHz and 5.8 GHz wont give you 15Km range. So this is what i advice:

Learn about FPV. Just look arround on the forums! Google and search what other people use and what kind of results they are getting. Before getting into FPV you will have to learn allot about it. And please don't skip this step or you will and up with the wrong equipment.

Start cheap! Use your 5.8 GHz and 2.4 GHz to learn about FPV and different antennas. Build helicalls and CP antennas, this will teach you allot about FPV antennas.

If you still want to go long range buy 433MHz RC (EZuhf) and 2.4 GHz FPV lawmate 500mW. If you are going to use a yagi you will need an antenna tracker. This will cost arround 1000$ to fly 15Km. Also it's not legall to fly out of sight! I do it but I only do it with gear that I can trust. Also for these frequencies you will need a HAM licence to stay legal with your RC and FPV gear.

Allot of people are getting into (long range) FPV because they watch videos from trappy. Allot of people buy long range FPV gear and after flying about 20 times they are starting to get bored of flying long distances. It takes allot of time! Can you tell me more about your experience with FPV?
