Post have room for 60ft long leg and 30 ft long in a vee shape
have room for 60ft long leg and 30 ft long leg in a vee shape at about 7/8mtrs above ground.
Not well up enough to know best way to feed it, ie direct feed with coax or 300 or 450 ohm feeder.
What are thoughts please M0GIB David.

What bands? Is the "Vee" looking from the side or from above?

I have a few wire aerials up.One which might be of interest to you is the aerial I fitted up a couple of years ago.Its 66 feet end fed with a unun on the end of it.It is fed with coax.It works well but I found that my Auto ATU was no good,I had to use a manual ATU.But at least its another type of aerial for you to give some thought to.

David,

If you treat it as a 90ft doublet and centre-feed it with 450 Ohm ladderline from a good external tuner you should get all bands 80m thru 10m.

Alternatively you could make it an OCFD - 44ft+22ft - and feed it with coax plus a 4:1 balun. That would give you 40m, 20m and 10m, and possibly 15m.

look at M0CVO Antennas they do A 42HP 40-6m but they work really well on 80m with a tuner if that helps.

Steve, can you recommend a good external tuner?

That's is roughly what I have found works best in my limited space.
I can tune 160-6m with any of the built in auto tuners, and it works well on 40 & 80 as well as the other bands.

I use some of the coax as part of the aerial, I have 8 ferrite snap ons about 20' from the feed point, and it is fed with a 5:1 unun.

The feed point is about 5' off the ground, then it goes up a fishing pole, over the roof to a tree in the front, where it is about 10' off the ground.

Out of all the wire antennas I have tried, it is by far the best, and simplest.

SGC230 every time. They'll tune a paperclip on top band. Put it at the antenna feed point, in other words connect the legs of the antenna directly to it. Massively reduces coax feeder losses.

I have an LDG RT-11 which works very well.

It can be used remotely, ie at the feed point of the antenna.

It is not perfect, as it needs to be sheltered from the rain (£1 pound box from poundland) as it has SO239 connectors.

I paid about £80 by the time I had made a control box and made up the remote cable. If you have a shed at the end of the antenna, it won't need a box.

I stopped using it, as all the rigs have built in or external tuners in the shack, which have memories for quicker band changes ( why that matter, I still need to work out :) )

I don't know if I am losing anything, but if I am I can't notice.
