[K3PZN-List] FD Antenna Location Thoughts

[Steve S]

Don't forget about 20/80 cw. I could share the west most building. Probably would want to space 80 cw and phone but quite possible we would be ok near each other. I'll be using inverted vees. If time/space permits may put up 160 dipole also.

Curt,
At the last meeting we talked about a 4A and 5A with Ray. #1 - 6M - N3VOP#2 - Digital - N3VOP#3 - 10/80 - William#4 - 40 - WO3L  (I think) #5 - 20 - Ray
If Ray does not make it then someone else can pickup on 20 and run with it.
In keeping with your comments on setting up the stations in a North/South line I looked at the site on Googlemaps and I have the following suggestion. I could not copy from Googlemaps so I will do my best to explain each building to use.
The 3 small buildings on the south side (rt 32 side) I will take the one the most west.
Next, just beyond (north of) the 2 large buildings in the center there in a small building by itself that would be #2 for William or Andy.
Then, use the stage for the next station and have the antennas north of it in the grass along the fence to be used for CW.
If Pat does make it to FD and wants to try his satellite station again he could take the same building as last year and have open space for the antennas.
At the meeting we talked about who would setup what band and mode BUT we never talked about placement of those stations. I agree with the north/south alignment to cut down on the interference. This may not be the best lineup for us but we need to think about it before we start unloading and stick to a plan and not change on the fly.

The straight line arrangement will reduce coupling.  20m and 15m are our critical bands in this regard.

> I am less concerned about 40m and 80m because the higher QRN masks some of the noise we share.  But we should try to put the low band digital antenna into the same line as the similar antenna used on SSB, so that we won't share noise on 40m.

> A little thought now will help -- and also hopefully minimize how many masts we must install.  Take a look at the W3AO site - you will be amazed how they fit the antennas into fewer masts and space, yet co-exist.
> A straight line arrangement of our 3 primary SSB/digital masts across the longest line we can muster does seem to make sense.
>
> We can also spectrum manage so that digital and CW are not both on the same band -- most of the time we should have 3 open bands, and we can trade spectrum through the day.
> 6 Rigs -- we need to gather about 12 ops or more -- even with 6 'iron people' available Saturday night.  Any chance that you the reader could join us ??
