Ham Radio - The Slidewinder Coil.. the ATAS 120 killer?

An enjoyable morning working some DX and European contacts on 15 and 20m, plus short skip openings on 40m.
In this configuration, when ‘static mobile’ (portable), the antenna operates just as a manual screwdriver antenna, but with three BIG advantages over antennas which are at the cheaper end of the screwdriver market:
EFFICIENCY - Firstly, it’s much more efficient than say an ATAS on 20 and 40m owing to the 2.7m (9ft) long whip. (Around 3-3.5ft longer than an ATAS).
COST - Secondly, the price.. £85 bought me the coil, 9ft whip and mag mount. This amounts to around $120 US. This is less than 30% the price of an ATAS 120.
ADAPTABILITY - this system can be used with various whip sizes (9ft is probably the maximum recommended length) AND is not dependent on you owning a Yaesu radio to use it (as per the ATAS).
Sure you’ve got to jump out and move the coil to tune.. but once you become familiar with the settings per band it’s a real keeper!

I have tried both side by side many times and every time the atas receives better and is a push button tune, as long as you take your time to install it :)

Some cracking contacts there Tim. I am away on holiday at present and have been using the slidewinder and mil whip. A couple of POTA activations and also whilst sat in the sun at the caravan. China, Canada, USA all in the log, all on 20w. It is a good little package of an antenna. Thanks for sharing, all the best, 73

Awesome! Nice to see a bit more of the antenna and set up. Great contacts made to New Zealand and Japan. I need to find a better way to tune up the Slidewinder as I don't have an antenna analyser to check it so relying on the SWR meter in FT857 only and having used it a few times have a rough idea where the slider needs to be. Nice one! 👍

i guess the antenna is only capacitive coupled to the chassie of the car. I have an ATAS120 and I’m very pleased. The real advantage is the free hands operation. You can tune it wherever you need with the touch of a button and don’t need the extra gear to analyse the swr. Even tough you should avoid tuning while driving sometimes I do it at low speed not to overload the motor. It works flawless.

I feel sunroofs need to come back into fashion. Back when I was first licensed (Class B), the antenna I built for 2m was a 2 element quad on a plastic pipe. I used to hold it out through the sunroof on my dad's Ford Orion up on the hills in South Wales, and thus had an "armstrong" rotator.

Brilliant one Mate catching Brian & Ron, I've worked Ron twice but yet to work Brian. I have no issues getting out to change bands when portable. I can do it in seconds with no SWR meter needed. For a long time thought about making a video on what people covet most in an antenna and it has nothing to do with how it performs.

Hi Tim, have you managed to try just the whip section of the ampro ham stick with the slidewinder, I’m curious to know what the results were if so !
@timg5tm941
@timg5tm941 8 месяцев назад
Yep totally doable .. ok for 12 10 6 .. will work on all lower bands too but more of a compromise as you approach 20/40
@G4VYC.
@G4VYC. 10 месяцев назад
Great contacts Tim, I have the slidewinder but use a telescopic whip fully extended to 5 meters, is it better to extend it to only 9 ft. and use the coil to resonate? I always thought more metal in the air was better. 73 G4VYC
@timg5tm941
@timg5tm941 10 месяцев назад
Hi Vic it depends on which bands you wish to use. Using the 9ft tank whip and the coil, the antenna is a tad long for 10m so produces a SWR of 2:1. Once the whip used exceeds a quarter wave long for a band and you use this with the coil, you’ll likely lose that band. So for example a 5m whip with the coil is likely to tune on 20/30/40, but you’ll lose a good match above 20m.

You had a pretty good morning and shows how well you can do with a portable set up. Please can I ask how many of the car park locations you use have height restrictions? I'm asking because I'm building a ham van/camper and lots of my local haunts restrict height to 2m or 2.5m which is too low for my Fiat Ducato.
@timg5tm941
@timg5tm941 10 месяцев назад
I never have it installed when on the move so car park heights aren’t an issue. Of my three usual spots, 1 has a max height.

@@timg5tm941 Thanks Tim, I wouldn't be moving with the antenna up, it's just a matter access given the height of the vehicle. Councils put the restrictions in place to stop encampments establishing but it causes a problem for legitimate camper vans and van users.
