THE AERIALS AT MY QTH

2 METRE COLINEAR

Pictured here is my 2 metre collinear. This is the Cushcraft ARX2B, known as a Ringo Ranger. It’s the best omni-directional aerial I’ve ever used. I would have like to have stuck it on the chimney, but I don't think the neighbours would have appreciated it. So it ended up on the back of the house.

From my QTH in Worthing, Sussex, I can work through most of the repeaters along the coast and several inland. This is also an excellent aerial for listening to the VHF marine frequencies on my Yaesu FT1500M.

What I have put on the chimney, and got away with it, is my homebrew 4 metre dipole. It's a shame that 4 metres isn't used more as the coverage is far greater than 2 metres. Sadly, I'm crystal controlled on four FM on 70.40 mHz. I monitor this FX just about all day every day so, if you have the gear, give me a shout. There's no picture of the 4 metre dipole as it's pretty boring!

On the right is my 10 metre halfwave vertical. Rising majestically from the trees, reaching to the sky like a phallic symbol... OK, so it's a CB-type aerial sticking out of the trees at the end of the garden.

The top of the aerial supports the centre of my 150 foot end-fed wire which I use for 80 metres and top band. You can just see the plastic tubing taped to the aerial. What a lash up!

Having said that, I've had some great results with the 10 metre aerial. Working through the US repeaters on 10 metres, FM simplex... 10 metres is great, when the band is open.

But this aerial also works well on 12 metres. I've worked down into Indonesia with no problem. And, although this is cheating, with a decent AMU I've used the aerial on 15 metres with great results.

Anyway, enough of that.

20 METRE QUARTERWAVE

This is the base of my quarter wave vertical for 20 metres. Notice the lettuces to the left? They have nothing to do with the aerial, of course, but they're coming on really well. They are Web's Wonderful, and were grown from seed in the greenhouse.

OK, back to the aerial. There are several wires fanning out beneath the ground from the base of the aerial. Nowhere near enough wires, I'm afraid. Obviously, the more wires the better. That's another job on the list.

This aerial, although ground-mounted, works extremely well. In fact, if you check out some of the manufactured vertical aerials, you'll find that they are exactly the same as my copper pipe. OK, so they have traps etc to work different bands, but at a cost of some £200 or more ??? I'll stick to my pipe!

Here is the centre of my 40 metre dipole showing the coax coiled up to form a balun and a choke to prevent the outside of the coax radiating.

I've now taken this aerial down and put up a doublet around 98 feet overall length and fed with 300 ohm ribbon. It works extremely well from 40 metres to 15 metres, and exceptionally well on the five megs spot frequencies.

40 METRE DIPOLE

 

Here is the centre of my 98 foot doublet aerial hanging from the two metre collinear. Fed with 300 ohm balanced line, the centre is about 25 feet above ground. The aerial works extremely well on the 40, 30, 20, 17 and 15 metre bands. It also works very well on the 5mHz frequencies.

Yes, I know there's a spelling mistake on the picture...

 

 


Here is the "white stick" 70cms aerial. At the moment, it's clamped to the fence. But it's soon to go up on the side of the house.

From Worthing, on the Sussex coast, I can get into the Isle of Wight repeater and the Newhaven (Lewis) repeater. And the base of the aerial is only ten feet above the ground.

Just look at the cloudy sky. This is the middle of August! Where's the bloody summer got to?

 

 
 

 

 

MY 5/8 WAVE 20 METRE VERTICAL

This picture on the left was taken just after a major thunderstorm. Wow, just look at the way the pole climbs majestically up to the thundery clouds. Needless to say, the aerial wasn't struck by lightning. On the right, there's a nice blue sky. I've also loaded this vertical up on 5mHz with some success. This will be good for the USA stations and probably Iceland, Finland and Norway.
