  QRV on all bands, even with restricted space... the BB-7V antenna is 6.7m long and has a max. power load of 250W PEP. The SWR above 3MHz is, depending on surroundings, at 2:1 or better. On some bands a simple tuner is required, the built-in tuners of many rigs are usually sufficient. The BB-7V is a wideband antenna, so it works also outside the amateur bands. Simple installation, no alignment required. The antenna does not require radials, the radiator is grounded.
Connector PL jack, the small transport length only 1.3m makes this antenna also suitable for camping or other portable uses, weight 3kg.

Vertical antenna for shortwave and V/UHF. A small antenna for radio amateurs with space restrictions. Allows operation on 80, 40, 20, 15 und 10m, plus VHF 2m and UHF 70cm! Gain on 2m is 2.1dBi, on 70cm 5.5dBi. Max. power 200W SSB (3.5 - 50 MHz), 150W FM (50 - 440MHz). Total length 2.7m, length of five lower radials approx. 1.5m, weight 2.4kg, max. wind speed 125km/h. For operation on HF no further radials are required! The center frequency can be adjusted for each band. Due to the shortened design of the antenna the usable bandwith can be limited, a tuner might be required.

Diamond multiband vertical HF antenna with shortened radials for 6, 10, 15, 20, 40, 80m. Total height only 4.8m, length of radials approx. 1.8m. Usual high quality finish and easy mounting, as known by Diamond products. Max. power load 200 W PEP, SWR <1.5, tuneable by adjusting lengths of radials. Includes mast clamps (30 to 62mm) and PL connector. The radials can be installed on one side only if space restriction requires. The radiator of the CP-6 is DC-grounded which gives a good protection against static charges and nearby lightnings. Please note the variants of the 80m radial. The new "S" version includes material which allows an isolated installation of the antenna to the mast. This reduces the influence of the mast to resonance of the radials, which in turn eases the tuning of the radials. For the same reason a short cable with a choke is included in the shipment.

• CP-6 80m Radials
• Standard 80m Radial as supplied with CP-6 (Article 11225)
  The standard 80m radial is tuned to around the lower end of the 80m band, i.e. the CW DX range from approx. 3490 to 3520 kHz. This radial can be tuned up to approx. 3550 kHz.
• R-1 Radial
  Optional 80m radial for 3575 to 3650 kHz for CP-6. For a better resonance match in the upper CW range, digimodes range and lower SSB range. Replaces the supplied standard radial.
• R-2 Radial
  Optional 80m radial for 3650 to 3725 kHz for CP-6. For a better resonance match in the lower and mid SSB range. Replaces the supplied standard radial, included in article 11225.R.

CP-5HS

High power version of CP-6, a little bit shorter, without 80m band.

Antenna for 7, 14, 21, 28 and 50MHz, length only 3.6m, max. power load 500W SSB on 28/50MHz, 400W SSB on 14 & 21 MHz, 200W SSB on 14MHz. As with the CP-6 the radials can be mounted on onde side only. Max. wind speed up to 160km/h.

Radialkit 80/40/30m

Radials for vertical antennas. Consist of two λ/4 wires per band. Uses PVC coated braided copper wire 1.5mm². Includes solder lugs on one end for easy connection to ground post.

These radial kits can be used for elevated antennas (not ground mounted). The radials should be installed so that they do not touch the ground, nor the roof nor any other obstacle. If the vertical antenna should be installed on the ground other radials are required (at least as long as the antenna is high, better longer, as many as possible, not less than 10).

Excellent explanations about antenna radial systems are provided by some manufacturers, for example by SteppIR and Bencher (english text):
