Post 4 mtr band,what's it like?
Before I make or buy a antenna for 4mtrs is it any good?!!
Is it a well used band generally? I'm only thinking about a vertical,what kind of distances are possible?
Cheers John

If your prepared to switch on and expect white noise for around 97% of the time then it's the band for you, expect nothing unless theirs a lift or contest I tried it and I had some fun but you have to be very patient, I'm a 6 metre guy very much the same but I'm willing to sit it out on 6 and that's enough for me these days.

Cheers Mark.
Just thinking its a fairly small antenna, might get away with no groans from the
neighbors?!
Most bands gloomy here at the mo.

4 and 6 are hard work but can be really rewarding they are bands that light up and suddenly go dim mate a bit like 2 metres one day you talk to france the next 60 days you hear nothing but the odd UK ham.
I would concentrate more on 2 metres if size of the antenna may be an issue least you will find the odd local on 2ssb or cw more so than 70mhz.

You've not said what modes you are thinking of.

I can only speak from my experiences.
Around here there is some activity most of the time.
There are regulars locals chatting, on both FM and SSB, in addition there seem to be some who use it on a daily basis to the southeast of me. The way the beam is generally parked.

Once the band opens it ca be difficult to find free space and, unlike 2M, or 70cm, there is the regulate chance of DX on FM.
Irrespective of conditions there's regular MS activity.

What you get out of it very much depends on how much effort you put in.

Check out http://www.70mhz.org

Cheers

Tony

What Tony said, I am only active on 70MHz FM mobile these days until I get my homebrew rig and portable station finished then I will be back on using SSB and Meteor Scatter modes.
I was pleasantly surprised on Wednesday just gone whilst driving back to Newcastle from Coventry, I called CQ on 70.450MHz just south of Tamworth on the M42 and G6MWS in Derby came back to me, had a half decent QSO.

I did notice several stations calling on 70.450MHz all the way up the M1 just north of Cheshire, at which point nothing more heard despite calling CQ every so often until Durham services at which point I gave up.

The band is excellent for all modes and station types, the problem is the lack of humans.

Rob.

I know there's the new FMAC for an hour, but is there much FM activity during the main 4m UKAC?

I'm just wondering if it's worth heading out for the whole evening, or just setting up /P locally.

Probably is, the beams are small and easy to build, so not expensive.

I listen on .450 all the time the shack power is on, on a vertical that is only about 15' off the ground, and I would say that I hear something every day round here.

I took down my 6&4m dual band beam, so no longer have a beam for 4m, but even with it being only 18' high when it was up, there was a fair amount of activity during contests and the odd bit at other times.

If you build one, try to use a design that does not need any metalwork for matching, makes life a lot easier :)
3/8 tubing for the elements and 1" square tubing for the boom works well, light and not too visibly ugly

I used to work a few FM stations, in the UKAC, but none last week.

It remains to be seen what impact the changes have as, at the moment, even the FM contest is dominated by those who are active on the band in both modes.

One or two who have done both sections said that changing polarisation was too time consuming and will run just horizontal polarisation in the future.
I've no verticals here so I don't have the choice.
We'll probably have to wait for the better weather before we can really assess things.

Cheers

Tony

Thanks for the info Tony, I'll look to try a horizontal dipole for the FMACs when the weather allows.

I'd try both polarities, on FM, to be honest.
If you're just using a dipole the cross polarisation losses could be even more noticeable.

Cheers
