You should build this type of antenna for one of your transmitters. It is Omni directional, most antennas for receivers are directional like log periodic dipole array (LPDA) “Shark Fin” antennas.

SMA connectors do have a 500 “connection cycle” rating. I have made SMA antennas and can say from experience the soldering the SMA connector pin on to steel cable can be challenging. Also the wax like material that forms the dielectric insulator is made of polytetrafluoroethylene. I had to look that name for you, it is not on the top of my mind.

Please help the sound community by purchasing your gear from dealers that support the professional sound community. Gotham Sound Trew Audio Location Sound Corp and Pro Sound (Florida) 954-289-4770. Good luck on your gear research.

I have built BNC antennas before. Here is a photo of a BNC antenna that I made attached to a Lectrosonics ground plane antenna.

Rachel, Replace the metal screws with nylon screws. They still may burnish the finish of the microphone. Good luck. mark

50 Ohm coax.

You can see that soldering on the circuit board one needs to be very precise. This is a G3 I did a few years ago.

What I think Glen was meaning to say is a dipole antennas made from 50 Ohm Coax cable. The Lectrosonics YouTube site has a DIY video on the subject.

Wilcox Sound will re-wire your Cos-11d for about $150 if you still think there is some life in it.

Judge, There is a lot of information on this site with regards to your question. Use Google like this> gain staging jwsound or g3 set-up jwsound The key is to not use the internal search tool from this site. Once you know the secret there is years of good reading and knowledge here. Good Luck

https://www.lectrosonics.com/US/wireless-guide.html This Wireless Guide by Lectrosonics is a good starting point.

Jon, I had an internal boom cable that had a nasty kink in it. I coiled the section along a smaller diameter wooden dowel, then heated it with my hot air gun. It got pretty warm, then I plunged it into a bucket with water and Ice. The cable came back to the original form. I hope this helps. Mark

Roubi, I have made antennas from nitinol nickel-titanium wire, but decided to use small diameter multi-strand cable instead. I understand that you are making antennas for receivers, not transmitters at this point. When I made nickel-titanium antennas, I would file a series of small notches in the terminal end of the wire. The notches would be covered by the SMA pin after soldering, but would add a mechanical bound inside the soldered connection. The colored caps are sold at B&H in New York, made by Lectrosonics I think.

Roubi, Here are some of the antennas I make. One of the tests I do is to put the SMA connector into a vice and then I lock vice grip pliers on the antenna wire. I then try to rip the antenna wire out off the SMA. Lectrosonics antennas are super strong. I pulled a Remote Audio antenna wire out, but it was difficult. Mine are 3rd place so far. You might think it is crazy to put a $40.00 antenna in a vice and then try to destroy it, but I wanted to know. I also did not want "talent" pulling an antenna out.

Hi Martin, We will just have to see how this all plays out. Mark

I agree Constantin, time code is vital. The Zoom F1 reminded me of the unfolding saga of the Tascam DR-10C and the Lectrosonics PDR. My comment attempted (from memory) to quote LarryF when discussing the new PDR. Here is his quote, "A recorder with time code is a recorder with time code is a recorder with time code. With apologies to Gertrude Stein." For our members that are not following this story, my references might be too oblique, my apologies. This might be a clue why the Zoom F1 does not offer time code, but also their target market and price point are factors to. Mark

Zoom F1, a body pack recorder with both audio input and audio output. I wonder if this will help Lectrosonics?

I rewired my with straight cable.

OP Just because a person can purchase professional wireless equipment, does not mean they understand the principles of radio gear. In my opinion there are plenty of people that start posting about gear problems before they have done enough problem solving themselves. Many owe manufacturers a online apologie.

I just purchased 1 of the SGS split-mounting top for a MKH70 on a Rycote blimp. Rock solid.

I think Samy's camera has a store in San Francisco. Adolph Gassers is closed.

I found 4 vintage Lectrosonics A-GPU ground plane antennas this year. They are a great addition to my kit. Thanks for sharing your excellent metal-working. LectroAGPU.pdf
