thanks again thermosstoys- somehow missed your post/wasn't notified..
the 2.4 GHz 8 dBi Circular Polarized LH Flat Patch Antennas- looks interesting- I take it that the 'LH' means it is indeed Left Hand circularly polarized as it doesn't confirm on that page
Correct, LH = Left-handed- very tempting if it is..this is a
directional circularly polarized patch (non omini/cloverleaf or skew planar) ?
Correct.Any estimation on what kind of range this could provide?
I could do the math or guess, but best to test. If PVFlyers results are any indication (he is using LH Helical's) the results will be better than the 14db TPLink, with a smaller antenna.
At this stage thinking of just modding 1 of the ports on the repeater for now with the ufl to RP-SMA connector (leaving the other stock antenna in the repeater as it is for close in diveristy)- and having swappable plug n play' antennas for that one port for different applications - not modding the p2v camera/vtx antennas at this stage...
Sounds good, just remember to have an antenna attached to the port before turning the repeater on.
I have the 14 dbi tp link linear patch antenna which is huge (not sure how to mount to a tripod let alone the repeater)-
That's a good antenna, yes it is huge. Some are taping / velcroing it to the front of the repeater. Others are using gopro mount and taping the repeater to the back of the pad it is normally attached to (better solution). Of course you could separate it and mount it to a tripod.and perhaps a 5 or 9 dbi linear whip for closer in ops and potentially this 8 dBi Circular Polarized LH Flat Patch Antenna you posted..and may likely experiment with the 1W argtek amplifier and 6dbi attenuator mentioned earlier between the repeater's modded RP-SMA connector, attenuator and antenna..
Lots of confusion, the Argtek is a repeater, you use it instead of the stock repeater not with it.just to be clear of the order- do I fist connect the amplifier to the modded RP-SMA connector on the repeater, then add the attenuator and then the antenna on top of the attenuator or does it go in another sequence?
If you use an amplifier (not a repeater like the Argtek, but an actual amplifier / booster, like a Sunhans, you would go from the RP-SMA connector on the stock repeater to the attenuator then to the amplifier / booster then an antenna on the other side of the amp / booster.
Someone on another post said just adding the one 14dbi tp link patch has created 3300ft in range alone (no other mods to repeater or p2v vtx/camera)
Yes that is a good antenna, however at 2000 to 2500 feet I needed to fly sideways to go over 3000...adding an amplifier will possibly add a lot more?
Will give a little more, but amplification is not as important or produce results like antennas (on both sides).I also heard the stock TX 5.8GHz antenna's range is around 3300ft-
Two days ago I went over 2 miles with the stock TX, But I have also lost connection at 1.1 miles (see: viewtopic.php?f=7&t=6446 so if I start exceeding that, then I'll consider upgrading that antenna, probably to a higher gain whip than a narrower radiation patch..
ps- the attenuator ebay link you suggested
http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... OC:US:3160 is down for the chinese new year..found this instead- will this work too?
http://www.ebay.com/itm/RF-Coaxial-Atte ... 1252558899 Yes, that will work.
edit: what about this sequence of parts if adding the amplifier in this order- first make the ufl to male rp sma mod/cable on the repeater- then attach the argtek amplifier (with a rp sma female to male adapter which I already have)- from amplifier to attentuator, I will need a rp sma female to sma female adapter-
http://www.readymaderc.com/store/index. ... cts_id=432 then add the 6db attenuator (connecting male sma end to aforementioned adapter) and then I'll need a sma male to rp sma female adapter like this
http://www.ebay.com/itm/SMA-Male-To-RP- ... 1e7df38cde and then I can finally attach my antenna of choice via it rp sma female connector to the last adapter.. (phew).. does this right to you- pretty compicated and lots of research- just hope th sis right..?
by the way- for everyone keeping their stock repeater- someone else in another post suggested simply keeping the stock repeater plugged into a portable USB charger to maximize range as range is known to drop as the repeater's charge drops- ordered this portable USB charging pack (in white of course) for only $5.99 shipped to do this-
http://www.ebay.com/itm/171187642605 - will this be necessary with an amplifier in the mix on the repeater?
Gratefully,
Justin
