Cushcraft R5 maintenance and repair
All R5 parts of the model. Additionally there is a flat angle of the MAV for transmitting. Near the foot of the R8 is a matching network. On 20 meters you can select the top KHz or bottom KHz of the band.
I replaced the two 86 pF caps in series with a single transmitting high current 47 pF doorknob type. The aluminium durability is good but not as good as Fritzel’s tubing. Leaking spots are the heath shrinks tubing over the bolt onto the connection of the coil former with the tube. The only fly in the ointment was the missing bottom mounting rings – but these were quickly sourced from the Cushcraft’s UK supplier at reasonable cost excellent customer service – well done!!
It is lightweight and easy to mount for portable or permanent installations. I’m running a GX2 and matching auto tuner at 10 watts into it at the moment license restrictions but have been able to work plenty of stations. MFJ should worry about their quality control.
Have chshcraft my FT with other hams and their antennas and the receiver checks out fine. I haven’t got another antenna to compare it against yet, but I have noticed despite my best efforts to isolate it from all sources of RF the output from the radio is full of white noise etc.

One end is sealed with heath shrink tubing and the other end is protected with a cap. There are no traps used on 6, 10 and 15 meters for maximum efficiency and power handling.
When this one finally dies, I will be done with Cushcraft antennas. One capacitor failed because of a burst cap and water get into the coaxial system. This product requires special order. Not the first time I have opened a Cushcraft antenna box and was left with missing parts.
I tried on my roof the diamond cp-6, also self-built by eantennas specifically the 13m long and 6 to 80m.
Adherence to the measurements give in the instructions makes life easier as does the cusshcraft of an antenna analyser! My rigid dipole is deaf to the side of this antenna. I give cushvraft R a big thumbs up!! If you have any questions, problems, or suggestions about Reviews, please email your Reviews Manager.
