VHF and UHF separate antennas

This works well for us in Adelaide metro area.

VHF antenna model DR3006. Channels 6 -12. 6 element - one driven element, one reflector, four directors.

UHF antenna model EE06. Channels 28-69. 4 dipole panel array with each dipole also having a director element.

Although the DR3006 is a small VHF antenna intended for Ch 6 up (digital channels), enough signal was available from it on Ch 2 (analogue).

This meant that a longer Ch 2 antenna wasn't really warranted for Adelaide metro area at our location. 

There is virtually no ghosting with this antenna.

VHF gain is 8.1dB (additional specifications below).

The EE06 is a 4 dipole panel reflector antenna.

Panel antennas are one of the best designs around and are used in various forms for TV transmitter antennas.

They yield a very high gain with simple construction and offer good immunity from ghosting. 

The bow tie driven elements provide a very broad continuous bandwidth.

Director elements are mounted in front on the driven elements to increase the gain at the high frequency end.

This helps to compensate for increased cable loss at the higher frequencies.

There is virtually no ghosting with this antenna.

UHF gain is 13.5dB (additional specifications below).

The two antennas are combined with a Matchmaster 09MM-UV1F diplexer.

The insertion loss is minimal and good isolation is provided between the VHF and UHF ports.

Community broadcast station Ch 31 is difficult to receive with a good signal in most locations in Adelaide.

This is because the transmitted power is much lower than other TV broadcast services.

The panel antenna pulled the signal out of the noise. 

The Matchmaster antennas use materials that are very sturdy.

The placement of the connectors and mounting brackets is well thought out making assembly easy.

They are very well engineered and provide an excellent result.

MATCHMASTER 

Matchmaster antennas. Serious engineering and high quality build products.

VHF and UHF combination yagi antenna

For those who want an easy solution.

VHF antenna section. Channels 6 -12. VHF gain 6dB. 4 element - two driven elements and two reflectors

UHF antenna section. Channels 28-69. UHF gain 11dB. 11 element - one driven element, 8 directors, 2 reflectors

Digital anti-reflection Matching System (DMS) achieved by diplexing the UHF & VHF antennas together, giving 20dB isolation for sharper analogue pictures and better Bit Error Ratio (BER) for digital transmission

‘F’ Type PCB Balun for quick installation & improved VSWR
Heavy Duty construction, stainless steel screws and Black ABS UV resistant plastics

Nitto Self Amalgamating Tape

10m roll (3/4" wide).

You need this for all the outside cable connectors, and nuts and bolts where connections are made on the antenna itself, to weatherproof them, otherwise the installation may only last a few seasons.

$19.95 per 10m roll

Fascia Mount 1.8m Galvanised

Suitable for most outdoor installations.

Secure with coach bolts to the fascia.

1. Heatshrink 25mm long is needed to make a professional finish. This can be 10mm dia for just the connector and cable or 13 mm dia if you want it to go over the connector nut to heatshrink the socket on the device as well eg antenna socket or diplexer socket. Slip the heatshrink on the cable.

2.Trim the sheath back 12mm

This is easily done with a box cutter knife.

Press down on the knife as you work it around the cable rather than use a slicing action, as slicing will usually cut the braid inside. 

3. Fold the first layer of braid back over the sheath to expose the first layer of foil.

4. Remove the first layer of foil by peeling it off the cable.  

5. Now fold the second layer of braid back over the sheath. 

6. Now remove 6mm of the inner insulation and foil, leaving 6mm of foil and 6 mm of inner copper exposed.  Make sure there are no foil burrs and that the inner and the foil are not a short circuit.

7.  Trim back the braid that was folded back to 6mm long. 

8. Fit the connector on to the end of the prepared cable. Note that the foil just goes inside the inner part of the connector and is not flared. 

9. Screw the insertion tool onto the connector and with a pushing and twisting motion work the connector on to the cable.

10. Remove the insertion tool.

11. Check that the inner white insulation is flush with the inner lip of the connector and if not repeat the previous steps 9,10. 

12. Crimp the connector on to the cable. Make sure that the crimp jaws are at the back of the connector on the part of it that will crimp readily and not the thicker part up by the nut.

13. Check the connector to make sure it is crimped correctly. The pin should protrude by about 1.5mm.

14. Slide the heatshrink over the connector and with the heat gun apply sufficient heat to make a satisfactory seal. (Or slide the 13mm heatshrink over the nut and connector on the device).
