Post Home Brew Vertical or Dipole for UkGen
Does anyone want to build a Dipole or Vertical antenna for use on the UKGEN Frequencies. I need to replace an existing one and I just don't have the time or parts to do it myself, So if anyone is around the Cheshire area and would like a nice little project then please contact me via pm.

Cheers

Not certain I understand the request.

What are UKGen frequencies?
I have always thought it was high band VHF, ie just above the 2m amateur band.

That would make it not amateur radio, also there are loads of commercial antennas available, which would usually cost less than paying some one to make one.

So I think I must be wrong about what the frequencies are :)

Will a dilithium xtal set send the signals faster or.just warp my key?

Just googled it, and the first item I find is something by ofcom published in 2999 (yes, 2999)

Yes, guess that would have been the best way to look at it.
But if you can build an antenna for 145 you can build one for 165 ( or 433-450)

You can build a dipole in minutes. Just buy a ready made dipole junction box....

https://www.ebay.co.uk/i/182327161000?c ... 497&crdt=0


Then cut the alloy tubing to length. Will cost you no more than £15 tops.... and take as long as it would take to hack saw through some 10mm tubing and clamp it in place... 10 minutes. Job done.

I'm assuming this is receive only... so you don't even need to be that accurate.

The OP is either very very busy or not bothered I guess.

I'm wondering what the profit margin in doing it would be. Be difficult to undercut a commercial aerial by much. I would always give a budget for this sort of thing, so people know what is expected.

Agreed, and if you do a good job of it, would likely cost more than an ordinary commercial one.

The whole question is a bit vague to me, a lot more information is needed to even consider if you would be interested in doing it, and then sending him a PM if you were.

I don't think many people have the time to do things like this as a favour, and it may well be for commercial use.

That's not really the point of self-building anything. However.... 10mm alloy tubing around £4 per 5 metres.... a dipole centre about £6 off ebay. Bolts and nuts etc.. pennies from a local hardware store.

:scratch: I think the op means HF . Perhaps he might originally be from N.America where AFAIK they refer to HF as the amateur radio 'general frequencies'

If that is the case then he might be looking for a compromise solution that could work on several bands such as a doublet,an inverted L or a loop

:blush: Could that be the case? Hopefully he will clarify .

I think he more likely means "simple light"frequencies that used to be called ukgen.
General frequencies to the yanks means the "general class"licence sub bands

He isn't self-building, he is trying to farm it out. We are not talking about making an aerial for yourself, we are talking a commercial venture (money changing hands). My post was, if you want a commercial aerial, just buy one, there are plenty out there. If you want, for want of a better phrase, a handmade aerial, then give a budget, so someone knows whether to bother or not.

Would be very interested to hear where you buy 10mm tubing for £4 for 5m, with delivery available. ( I assume delivery is available, bit pointless otherwise)

Aluminium Warehouse is more than double that, and their prices are usually pretty good.
