High swr dx patrol helix

hi.

I seem to be having a issue with high swr with the new dxpatrol helix, I sent email to manufacturer but still waiting to hear back.

Naturally I am eager to get up on the bird so said I'd post here in case someone spots something I'm doing wrong.

Iv tried different cables and its the same, initially I had it all mounted up on the dish and that's when I noticed I had high swr on tx, so I removed it and used a short cable to the dxpatrol ground station, still high swr.

Next I started to examine the antenna, I noticed that inside the flap was not making contact with the coil, looking at pics from dx patrol manual I saw their one was, so I bent the flap so that it makes contact but still high swr.

Ill attach pics of my one and the dx patrol one where you can see the gap in the flap and coil.

I'm using sma to so-239 pigtail>to coax with pl259s then to a so-239 to sma to sma to n-type.

Cable used ultraflex 7.

Anyone any ideas ?

Thanks

ahh I see, so you think this is the issue ?

What connectors would you recommend ?

thank you very much, I'll change to N

quick update, I removed the so259 and pl259, soldered coax direct to the pigtail cable...

Still high swr..

I have no idea on how this antenna design works as I am only new to the sats.

Its the new dx patrol helix

Hi,

the Helix has the right polarization. You should use a N-connector socket and an approriate cable.

Thank you for reply.

I have removed the so239s and pl259s, I have a n type to sma adaptor on the helix, pigtail that is directly soldered to ultraflex 7 coax. The other end has also direct solder to pigtail lead into the ground station

bug still HIgh SWR, the GS goes into protect mode

I'm running SMA pigtails because on the DXPatrol ground station it has an SMA connector for the 2.4ghz TX. On the helix antenna I'm using a n-type to sma pig tail that is going to the coax

I'm not using any connectors on the ultra 7, I soldered directly to the sma pigtail

ill take some pictures now of what I have might be best

did you measure the VSWR with built in LNB? I think this helix needs the LNB for correct working

I do not have a analyzer for the 2.4ghz range unfortunately.

Yes mounted on the LNB i am getting the high SWR as indicated on the Ground Station

again I dont have a dummy load.

Why do you have to use connectors on the coax, it should matter if there direct soldered or not I would have assumed. The issue was still here using the pl259s which is why I removed them as there not designed for 2.4ghz.

I really appreciate the help trying to get this working
