Shortwave Vertical Antennas from Cushcraft

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. I purchased the R with the same basic expectations as the older R7 I previously owned. The result is lower loss and higher bandwidth on these bands. The R has good performance, easy installation and use, slim silhouette and high reliability. The tube was removed, the inside of the insulator applied with layers of 2 component polyester resin until a minimum variation of fit.

My Account Cart Contents Checkout. I have a small, sloping roof, so I can only install certain antennas. There were no signs of failure on the traps or matching unit. Insulator protected with black non-metallic spray paint. It is rugged and not too tall mounting without guy ropes. It is lightweight and easy to mount for portable or permanent installations. Its now sitting approx 18 feet above the ground on a sectional, guyed tubular mast being fed by a decent length of RG I eventually had to cannibalize another antenna for the needed parts.

That is contrary to the print design. Works well on 30 meters with antenna tuner. I had a little difficulty opening the box at the bottom mainly due to the use of steel screws rather than stainless – but again, given that it had been in the air for some time this was forgivable – I swapped them over anyway as a matter of course.

Construction is good, not great. It is lightweight and easy to mount for portable or permanent installations. It is lightweight and easy to mount for portable or permanent installations. I give my R a big thumbs up!! Flash-overs when running high power shorted the wet capacitor out and evaporated a part of the insulating tubing.

Which on closer inspection of both the inst. It may be necessary at the band edges or with a transistor amplifier, that you have to use a tuner.

I tried on my roof the diamond cp-6, also self-built by eantennas specifically the 13m long chshcraft 6 to 80m. On 20 meters you can select the top KHz or bottom KHz of the band.

That was cyshcraft MFJ got a hold of them. It includes many of the features of the Cushcraft R8, R7 and R5 antennas.

When this one finally dies, I will be done with Cushcraft antennas. The result is lower loss and wider bandwidth. Yagi only outperforms this antenna if cushhcraft beam is pointed to the station. Have had mine a year and used an MFJ antenna analyzer to get all bands at 1: I’m not surprised, that’s quite a change in distance from 5′ so the tuner needs to be used on some bands. The R is reasonably priced and gives you a good price to performance ratio. The result is lower loss and wider bandwidth.

We had 1 of this item in stock at the time of the last update.

So the transformer step up ratio is 5: Those “radials” are in fact a top hat capacitance. One capacitor failed because of a burst cap and water get into the coaxial system. The polyester surface has the tendency to “evaporate” and the bare glass fibres then are like a sponge attracting absorbing dirt and moisture. A deep zero-point ensures that the antenna does not pick up the local QRM. The result was very pleasing. Purchased a new R in August of The R is a 6 through 20 meter, no ground radial antenna.

It ucshcraft lightweight and easy to mount for portable or permanent installations. I used a polyester repair set for automobile and applied the 2 component polyester resin with a brush.

I have not spent the money twice. I have a limited space here.

Once I’d downloaded the instruction booklet it became apparent that most of the hard work putting the antenna together had already been done for me: Also a dipole rigid self-constructed to All I can say is that for the money its proved to be an excellent performer so far, best of all none of my neighbors have complained about it: Leaking spots are cushcrft heath shrinks tubing over the bolt onto the connection of the coil former with the tube.

I’m surprised this cuscraft performance. You must be logged in to post a comment. Cleaned and repaired coil.
