I owed an R7 for a number of years in the 90’s and liked it a lot. I replaced the two 86 pF caps in series with a single transmitting high current 47 pF doorknob type. Have had mine a year and used an MFJ antenna analyzer to get all cusgcraft at 1: A Stormy New Year Vushcraft Email Subscription You are not subscribed to this review.
If you have any questions, problems, or suggestions about Reviews, please email your Reviews Manager. The antenna does not require traditional ground radials, so no need for unsightly radials and is so light a normal scaffold pole would be ideal to mount the antenna.
Leaking spots are the heath shrinks tubing over the bolt onto the connection of the coil former with the tube. It may be necessary at the band edges or with a transistor amplifier, that you have to use a tuner.
Most HF rigs today include the 6 meter band so this antenna gives you instant access to the “Magic Band”. The R was a replacement 60000 a MA5VA which worked very well but had power limitations and the reason for the replacement.

Please Select Alinco Alinco Closeout. Text Questions to This changed the dielectric constant of the capacitor, thus moving the resonant frequency, and the SWR increased dramatically. 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.
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 cushvraft. Machined aluminum clamps and UV stable insulators guarantee years of reliable service.
It arrived in a ‘used’ state and so I set to with wire wool, wet ‘n’ dry paper and finally metal polish and a mop. Customers who bought this product also purchased.
Those “radials” are in fact a top hat capacitance. In a residential area like here it is impossible to place large Beams. I have a small, sloping roof, so I can only install certain antennas.
This antenna is sensitive to metal objects in near field.
Installation instructions could be better, but take your time and it works. It includes many of the features of the R8, R7, and R5 antennas. The antenna wobbled due to the gap caused by evaporation of the polyester. A deep zero-point ensures that the antenna does not pick up the local QRM.

The 2 component polyester resin can be used in combination with fibreglass mat and fibreglass thin film to fill holes in surfaces of steel, aluminium, wood, concrete and polyester.
Construction is good, not great. It is lightweight and easy to mount for portable or permanent installations. I would never have considered buying the Cushcraft verticals until a ham friend started bringing his R6 out RV camping I took the antenna down and it turns out that water got inside a trap because cracked heath shrink tubing and a split in the joint between the coil former force-fit? Measuring the traps is only possible by comparison with another R5.
The R employs quarter wavelength stubs on 10 and 15 meters to replace standard trap coils. Top Five Amateur Radio Reviews of On the auto transformer are 5 black turns and 6 white turns through the toroid. R means excellent performance, easy installation and use, slim silhouette cushcrfat high reliability. For typical use the Cushcraft R requires no tuning. There are no traps used on 6, 10 and 15 meters for maximum efficiency and power handling.
But give her height at least 4. Be the first to review this item. The R5 is mounted on a 12 m mast. Use keywords to find the product you are looking for. It includes many of the features of the Cushcraft R8, R7 and R5 antennas. An adjustable tuning unit ensures cushvraft bandwidth of 40 kHz, which can be freely adjusted between 1. I purchased the R with the same basic expectations as the older R7 I previously owned.
HF Vertical Antennas Back. Purchased a new R in August of Customer specific antennas telescope antennas etc. While 10 meters has not been the hottest band in the Amateur Radio toolkit of late, Iran apparently has found it an ideal spot to operate various rada MFJ should worry about their quality control. R5 a 5 band vertical on top of a 12 m mast. The result is lower loss and wider bandwidth.
