Does anyone have a suggestion for a higher gain antenna for the BFD / BDR?

The following half-wave antennas can be purchased from http://www.digikey.com/ and will increase the range over the standard quarter-wave antennas:

 

Transmitter antenna: ANT-916-CW-HW-ND

Receiver antenna (Analog): ANT-916-CW-HWR-RPS-ND

 

BDR: ANT-916-OC-LG-RPS-ND

 

They are about twice as long as the standard antennas.

I just received both of the long range half-wave antennas that Jim listed above, and used them on a job today.  I started by first replacing the transmitter antenna, and kept the quarter-wave antenna on the receiver.  Mainly because the new receiver antenna is rather large, and I wanted to see how we would fare with just using the half-wave antenna for the transmitter.  

 

My 1st and I were very happy, not a single issue with transmission the whole day.  We were separated by thick concrete walls in the morning, and line of sight exteriors a few hundred feet apart after lunch, without any trouble.  I feel that with the standard quarter-wave antennas we would have normally run into some issues.  I will try and record more accurate results next time.  Overall, I think It made a difference, and if you use a Bartech it's worth it to have these in your kit.  They are cheap, and they shipped really fast.

I bought them as well. I haven't needed to swap them out yet as I have been in the studio lately.

They're in the kit and ready for the next time I'm running through an alley!

I am with Alan, haven't needed them yet, but they are ordered and on their way to be added to "the kit".

 

Sometimes I think McGuyver would be jealous of the amount of stuff that is in the kit.

Although mine is the 95th unit made (~13 years old), I loose a solid connection past ~30feet line of sight. it begins to lag, and sometimes not even respond in very very close distances with no interceptions.

I know it's quite a old post. But I was having what sounds like a similar issue with my unit. Loosing signaI at around 30 feet with a clear line of sight. Tried the long range antennas mentioned in this post and it only made it worse.

 

I took it down to Jim and he swapped out the receiver and transmitter modules. That apparently fixed it. 

 

He also told me that I can throw away the halve wave antenna for the Transmiter that I bought. Whose link is above. Just doesn´t work. 

Only the halve wave antenna for the Receiver is good to use.

Thanks for posting that Javier.  When I originally tested the longer range transmitter antenna it seemed to improve the range.  Later on I retested it and it actually made matters worse.  So I concur with Javier, receiver antenna yes, transmitter antenna no.
