I'm just sorting out my planing for the SSB Sweepstakes and came across your question on the forum.
Try the Austrialian Government Website.
This has tools for making real time predictions for HF comunication. I have just used the Combined HF Prediction Tool for the HF Amateur bands in your area for throughout today.
Even for me the site is fairly straight forward to use and has much information on it. But here is how I used it.
1) from the home page click on 'HF Systems'
2)Then under 'Online Tools' click on 'Prediction Tools'
3) Click on ' Combined HF Prediction' A Java aplet will start to run. Make sure that it is allowed to run. Also any 'pop ups'
4) Click on the 'HAP' button and the World map will appear.
5)Put in the Map location by one of three ways. Move your mouse to the location and 'Left Click'. Fill in the Lat and Long boxes. Or click on the 'Base Location' tab and type in/sellect the City from the list. Chicago and Boston are in it.
6) Click on the 'Frequencies' tab.
7) Click on the 'Amateur' tab
8) Click on the 'Date and T-Index' tab and select 'Northern Hemisphere' in the 'Current real-time T- Index section' button.
9) Click on the 'Predict' button. You will then be instructed to 'define the area' This is done using the Left Click of the mouse to form a box.
10) Click on the Predict' button and then a new web page will appear with four sets of prediction maps. Make sure 'pop ups' are allowed.
As far as suitable antennas are concerned. There is much infomation on the ARRL website. Including an article for Sweepstakes in 'The Doctors In'
I myself use an inverted V antenna at about 45ft. It is quite long ( 500ft) and so has many lobes on the 15m/10m bands. With propagation moving throughout the day. It can act like a 'search light' for my QRP signal to various areas of the USA. Helping me a little more, when there are large signals all around. The ARRL website also has an article on the design of a 10m/15m/20m two element wire beam antenna for the Sweepstakes. Hopefully I will have mine completed before next weekend. A few days ago I had a very low, at10ft, inverted V dipole as an antenna here in Europe and managed to work VE3, VE5, 9X, ZS, GI on 10m with 5 W. So there will always some close in signals getting through.
The contest is great for learning about local propagation. I know for my location during the short time the Greyline moves accoss my location I will get very good propagation on 20m,15m,10m up to WA, NT and AK. Before they disappear and I get great coverage to Australia and New Zealand. Last year 40m went long much earlier than I thought so I couldn't work stations which I would normally 300 mls away.
Look forward to working you in the contest
|Overseas Membership Fees, no longer such a bargain.||G0KZZ||on 28/7/12|
|A bit 'tongue in cheek' But many years ago I paid for life membership at Dayton which is very easy for the ARRL. At the same time I paid the same for the RSGB. Which was very difficult. One of the best things I did. The only annoying thing was that I did not realise (Its not published by RSGB or ARRL ) is that the the fees are tax deductable in the United Kingdom.
However the inability to download QST to a phone due to its new digital format is a real pain. I use the pdf versions up to 2012 all the time now. Please don't use a proprietry DRM. Logging into your website and downloading QST is easy and can be used on most devices.
Is there a lifetime subscription to QEX?
Maybe send out the anual CD with the Christmas edition of QST. there's one in each handbook and many other books
All the very best

Lay some perminent cables from your Park Home to a disguised post, Mail box, bird table etc. Where you park your truck. Then use patch leads to the equipment. If the HF set has a remote head you could just transfer this to your Park Home.
The other idea is to remotely control the hf equipement using a low power 2m or 70cms hand held.
Finally you may be able to try a magnetic loop antenna or a DDRR antenna as part of the roof of your Park Home. The ARRL website has plenty of articles. Try " A 40m DDRR Loop by W6WYQ"

|What is the secret to logging zones/sections close to your QTH?||Macromancer||on 5/7/12|
|Just found my Sweepstakes information pack I made up for the 2010 Contest. Other than the the rules, it contains some antenna construction articles. Which I hoped to try out.
There was also an article from the ARRL website entitled:-

|Longwire Antenna||WB8ZTP||on 4/7/12|
|I glad all went well. It's a very nice place to visit. I've worked portable there, when parked up on Route 12 which runs up Cape Hatteris National Seashore.
Because of the location surrounded by the sea you may find that a vertical antenna will also work very well. I used an MFJ 12ft telescopic whip ( the biggest I could get at the time) mounted on the vehicle trunk, a small matching coil across the feedpoint and a counterpoise wire when I operated there. A vertical dipole would have been better. But I had no supports. Something to think about as a backup if you can't get the long wire up.
The ARRL website and books have much information on antennas for use on the sea shore.
