noeld Posted March 29, 2012 Report Share Posted March 29, 2012 Has anyone used a jumper cable to move the zaxnet antenna to a different location in the bag? My bag won't allow for me to use the anttena in it's normal spot. I like the bag, I don't want a new one. I'm looking at these options on link and mounting in the bag. http://www.surplussales.com/Connectors/SMA-4.html Quote Link to comment Share on other sites More sharing options...

RadoStefanov Posted March 29, 2012 Report Share Posted March 29, 2012 I want to buy the 614. 1kg less then 601. Sent from my HD7 T9292 using Board Express Quote Link to comment Share on other sites More sharing options...
noeld Posted March 30, 2012 Author Report Share Posted March 30, 2012 I love the bag, but it's too tight for zaxnet antenna. I have a Cisco systems engineer working on a jumper cable. I'll let you know what I find. Quote Link to comment Share on other sites More sharing options...

I'll let you know what I find. see if someone with a 788 wants your bag, and order the 614a (a for antenna?). ebay is a source for jumpers if you have no luck. ao Quote Link to comment Share on other sites More sharing options...

bendybones Posted March 30, 2012 Report Share Posted March 30, 2012 I asked about this as I want to get this bag for my current 552 and imminent Nomad *, See post 56 in this thread Quote Link to comment Share on other sites More sharing options...
bendybones Posted March 30, 2012 Report Share Posted March 30, 2012 order the 614a (a for antenna?) Where are u finding 614a listed? I couldn't find it on Petrol site. Thanks Quote Link to comment Share on other sites More sharing options...

ao Posted March 31, 2012 Report Share Posted March 31, 2012 Where are u finding 614a listed? I couldn't find it on Petrol site. Thanks my dealer told me about it. I do not see it on the petrol website either. perhaps an nab launch, or they might sneak it in under the radar because of the oversight. the right angle connector on the ifb antenna takes up more space than one would expect. ao Quote Link to comment Share on other sites More sharing options...

Tom, Let me know after you test it. Also HOW MUCH? Quote Link to comment Share on other sites More sharing options...
Tom Visser Posted April 1, 2012 Report Share Posted April 1, 2012 Tom, Let me know after you test it. Also HOW MUCH? The two antennas were $11.19 for both and the jumpers were $7.99. Shipping from China was free too. The seller's eBay ID is "chinarf". I just did a non-scientific test, randomly tried two different frequencies and did a little walk-around-test at my home. With a few walls in the way, the stock antennas did very poorly and could barely get out of my house where the new ones were doing much better. I don't think they added significant range, big picture wise, but where the stock ones were failing, the new ones were still receiving strong, they would just fail a few more paces away though. Placing my transmitter outside, seemed to give me a range that was anywhere from 10% to 100% better, depending on what frequency I chose. The QRX-100 were being used as transmitters and the stock antenna was just placed on the right unit, where the new antennas were placed only about an inch away from the left side of the ZaxPaq. The stock antennas are omnidirectional low gain, where the 5dB is a bit more sensitive to proper antenna placement as they have null spots along the axis of the dipole (i.e. don't point the antenna directly at the receiver), but it is still pretty progressive and forgiving and appropriate enough for bag use, just make sure they stay more or less straight up and down. If figure if you put them up high and away from the bag entirely, it should do even better. I swapped frequencies on the QRX's then, to make sure I wasn't getting a result that was skewed by interference, repeated the tests, and they were more or less consistent with my original test. The open air range did not give me 100% improvement this time, though, something a bit less. I figure the next step is getting a bag friendly RF amplifier in there to muscle through any further range issues. Anyone have any suggestions? Even if they didn't improve range, which they did, it was worth it just to be able to put my antennas someplace more convenient and to not stress the bulkhead SMA fitting / nut on the QRX. The fit is still tight, even with the low profile right angle SMA. The back side of the fitting is basically snug up against the adjacent QRX receiver.

Cloud Wang Posted April 1, 2012 Report Share Posted April 1, 2012 me too made two of that jumper cables about 30cm and replaced my nomad's antenna to other place in my bag, cost 1.5 usd :-) so far so good Quote Link to comment Share on other sites More sharing options...
