You can also use these as loft aerials but the signal in the roof space is likely to be at least 3dB (50%) lower than outside.

Wideband Yagi aerials are NOT RECOMMENDED for regions which require a "Group A" aerial - such as Crystal Palace, Bromsgrove and Rowridge coverage area. Please select a "Group A" aerial or a log-periodic aerial instead. (Read notes click HERE).

Your problem:

You want to receive "Freeview" digital terrestrial television programmes but some bouquets are simply not available?

Or: You have always had grainy analogue TV pictures because you are in a poor signal area, or reflections from tall structures cause ghosting?

Your Solution

This is the Vision V10-040 log-periodic aerial with 40 elements

Log-P aerials are suitable for digital Freeview reception in 85% of the UK becaue they are inherently "wideband" (covering UHF channels 21-68) and inherently less susceptible to unwanted "noise" and interference than ordinary "Yagi" aerials.

In addition, they have a lower wind resistance (no rear reflector) making them just as suitable for mounting on a tall pole as in a loft.

The Vision V10-040 Log-Periodic is suitable for many situations, indoors or outdoors.

Meet the TEL13 Televes DAT45 Aerial (was PRO45)

Light enough for a 13 year old boy to hold on his fingers
Man enough to give you the powerful reception you need.

Constructed from aluminium alloy and BLACK moulded plastic, this aerial comes partially-assembled so all you have to do is clip on the reflectors and bolt it to a pole.

It looks good. It looks the business. It works. Your neighbours will come knocking on your door to watch TV!

* See notes below

The DAT45

• 16dB gain (max at 860 MHz)
• Substantial freedom from rearward and side interference.
• Excellent for Digital as well as analogue.
• Margin Raising Device (M.R.D.) available.

The M.R.D. has no effect on performance unless the 5487 power supply is connected. See notes.

* Please note:
Although this aerial is said to be better than a standard "Yagi" type aerial, results depend on location and can not be guaranteed.

NOT RECOMMENDED for regions which require a "Group A" aerial - such as Crystal Palace, Bromsgrove and Rowridge coverage area.

Please read further notes about this versatile MRD aerial and amplifier system DAT45 (and DAT75 below)

Safety

For your safety, we recommend you get a professional installer to fit any DAT aerial. To achieve high gain with minimum interference, it has a narrow capture angle. Consequently the alignment is much more critical than with an "ordinary" aerial.

Power Supplies

We offer a choice of two power supplies. There is no significant difference apart from the price. In some cases we may supply an alternative from the one you order. Both provide TWO output sockets and sent 12 volts up the cable to the aerial amplifier or MRD. It does not matter where in the cable you fit the power supply.

The DAT75

More Info

Sorry, yellow 1507 currently unavailable.

NOT RECOMMENDED for regions which require a "Group A" aerial - such as Crystal Palace, and Rowridge coverage area.

Requires a 2" diameter pole and substantial bracket if mounted outdoors.

• 18dB gain (max at 830 MHz)
• Substantial freedom from rearward and side interference.
• Excellent for Digital as well as analogue.

QR18 Triax Wolsey A18QR wideband aerial 12.4dBd gain, 30 degree beam, 25dB rear rejection.

Excellent performer where your postcode area is listed as OK for all Freeview multiplexes. 60% more signal than a standard "contract" aerial gives you that extra "edge".

Log Periodic Aerials

The drop-down list above includes some "log periodic" aerials. These are explained fully in "The Freeview Bible".

They are excellent in areas of moderate to high signal strength where good resistance to "impulse interference" is important. This type of interference comes from thermostats (aerial too close to mains wiring) and from passing traffic ignition systems.

They also have very low wind resistance and a very flat gain characteristic right across the band (unlike other aerials which may quote "21dBd" as a maximum but actually drop way down at high and low ends of the band)..

Vision Log Periodic V10-LP standard, 7.5dBd gain is a good quality aerial with "saddle clamp" connection at a "budget" price. It has a low wind profile so good for stormy areas.

Vision Log Periodic V10-LP super, 9.5dBd has a much higher gain with forty elements and "F" connector.

Vision Log Periodic V10-LP Pro, 8dBd rugged construction and dark green anodised so it is very discreet and protected from corrosion. It uses 18mm boom sections and has an "F" connector. Ideal for community systems.

See drop-down list, above.

Graph showing gain across the band from channel 21 to 69. This applies to the wideband versions only. Notice the typical gain "droop" at each end of the band. The highest gain is between channels 51 and 61. This is normal for a "yagi" type of aerial design.

Note: these aerials need a very stable mounting so use the largest diameter pole and keep it as short as possible.

Cable for Digital satellite and TV

To ensure the best possible reception you would be wise to use double-screened coaxial cable. No point in buying the best aerial then using poor quality cable! Read more about this on page 8

Short lengths (up to 30 metres) can be supplied.

Twin coaxial cable available. Clips available.
