does the antenna wire have to connect directly to the backstay wire, or can it be connected to the stainless swage fitting above the insulator?

Not sure why you would want to fit it to the swaged fitting. I've only ever seen it clamped to the stay, which surely is easier?

Attach to the the swage. on the wire you have a chance of corrosion due to disimillar metals

I see what your asking
The insulated wire for receiving can be wraped around the back stay or any other stay but then should jump to the receiver
If your transmitting then the insulated wire should be the same and to,the TX
On the receiver you can try attaching the anntena to anything thats metal and going up!Depends if your boats plastic wood or metal and if the mast is wood or metal
For receive the bigge the antenna the better for TX its better tuned;rx should be tuned but try and do as best

I might be missing something here (no expert on swaged fittings we have stalok) but the wire will be copper, the swaged terminal and the stay are stainless. Thus no difference regarding corrosion.

Just clamp it to the wire, no worries, thats how I've seen most done here.

Yep, agree with kellyseye and you. I don't think I've ever seen one connected to the swage. Not saying it wouldn't work, just that there's no point.
Another thought - the swage is effectively a (hopefully good!) joint between the swage and the backstay - so why introduce the possibility of increased resistance when you don't need to?

Clamp to the back stay works for me - dont forget to stand the aerial wire off, below the insulator. You can buy expensive ones or drink a lot of wine and use wine corks and tie wraps - this also works for me and either has a degree of yottie 'credibility' or shows I am an Alchoholic!!!!

Good idea about the wine corks. However the diagram in Mike Harris' book shows no need for spacers. What are they for?

Depends who you ask, I was advised they were not necessary by my installer. However everyone I have seen uses them and they seemed to improve my reception. I think the theory is to keep the aerial wire away from any potentially earthed source to either reduce interference and/or reduce the effectiveness of the insulation. I am sure others will know more than me.
