51 years old and paid for 50 years ago, it's probably pure profit right now. OH they will probably jack the ticket prices up soon too AGAIN !

Re: 2.4 antenna extension

Problem solved - I think I will post a new post with pictures on how to successfully get the antenna where you want it. I now have 1.8 km range on the end of a 4 foot coax

Remove the stock antenna at the solder points in the RX. stripping the end is difficult as it is tiny stuff. test fit it into place on the RX board. temporarily reassemble the rx without the antenna and drill out the hole to the same size as the coax. take it apart again and CAREFULLY solder it into place. it into the RX I used a 4 foot length SMA coax.

At the end that acts as an antenna, I was going to use the antenna off the RX but inadvertently destroyed it. having no other option I created the aerial from the coax. cutting apart my 9X RX unit I found it was made by cutting back the coax shield and leaving the center core (with the plastic shield) open. then they expose just enough of the outer shielding to slip a brass tub over and solder it to make a skirt that seals of any interference. I used 1/8 inside brass tube that fit with little clearance over the coax. Line it up with the exposed shielding - don't let the shielding stick out, it has to be level with the tube. Then solder the tube and shielding all the way around. I thought it would melt the plastic on the exposed pigtail but it will not.

Now the important part: don't try and get the length of the pigtail past the solder right before soldering, just make it long. Once it is soldered then trim it by comparing it to the one that came off. Keep trimming until they are the same.

That is it, like I said I will post pictures shortly on a new thread
