ST2 Scantenna Heavy-Duty Clone Coming Soon

#1 Post by trp » 12 Feb 2020 17:29

For those who don't frequent Radio Reference, there was an interesting post there this afternoon (02-12-2020) regarding an individual/company who will soon be manufacturing/selling a heavy-duty clone of the very popular Antennacraft ST2 Scantenna (which was also sold under the Radio Shack brand name as models 20-042 and 20-044). According to the RR post the antenna will be "built like a tank" using heavy wall aluminum tubing and stainless steel hardware.

There are 6 pictures of the prototype/first antenna at RR but they are copyrighted (copyright by Skyward Antennas) and it was asked in the RR post that the pictures not be posted elsewhere at this time so I am not attaching them here. If you want to read the original RR post and see the 6 pictures you can find them here: https://forums.radioreference.com/threa ... te.401714/

It's interesting, but I'd like to know the all up weight and the cost. I'd need some convincing to agree that stainless steel hardware is a real benefit. I do appreciate the idea of thicker walls. My last ST-2 was blown apart in a wind storm last fall.

I wouldn't expect this handmade antenna (per the info posted at RR) to be at the same price point as the previously mass-produced Antennacraft ST2 (or Radio Shack 20-042 and 20-044 twins). I am sure that the thicker wall aluminum tubing, aluminum plates, stainless steel hardware and handmade assembly will all add to the production cost of the antenna when compared to the original mass-produced design.

FYI the new antenna has been named The Searcher I by Skyward Antennas and they have just released a promo photo of the new antenna. The picture does not have a copyright notice on it so I have attached a copy of it below.

It appears that they plan on still using the wingnuts to hold the conductors. I was never able to get a decent weatherproofing on that and eventually the corrosion degraded the signal.

I get around that by using NoAlOx on it. (Electrical anti oxidizing compound used on SE feeder aluminum cables in electrical panels. also works well on Car Batteries to eliminate corrosion).
Goop it up, then wrap it up with Scotch 33. (Not generic tape, as it tends to break down.)

In the past I have had similar 300-ohm exposed outdoor antenna connections on a Grove Scanner Beam, Channel Master 5094 Monitenna and a Radio Shack 20-044 Scantenna. I used Coax-Seal (registered trademark) on all of those antennas with very good results that lasted for many years. Here's a direct link to it at Universal Radio if anyone is interested in further information or would like to purchase: https://www.universal-radio.com/catalog/cable/1194.html

It was just posted today (02-17-2020) at RR that the shipping weight of The Searcher I antenna is 6 lbs. while the original ST2 antenna has a shipping weight of "just over 1 1/2 lbs."

It was also posted that the new antenna will be shipping from zip code 44431 (Leetonia, Ohio) with sales tax being charged only to those in Ohio. The actual selling price is expected to be announced "soon."

I'm not an engineer by any stretch of the imagine, so I have to wonder how that much weight is going to affect wind loading as well mounting considerations for most scanner enthusiasts.

$30.00 shipping to the West Coast translates to about the same amount to the East Coast. Still no word on price for the antenna itself.

Not unlike the Kreco line of discone antennas. The 100-800 MHz ships at 12 lbs, the others at 4 lbs. They are made for commercial use. $600+ discone

And remember that something this heavy, when mounting, you must consider both wind loading and ice loading, which will make the antenna easily 4x the listed "dead weight"...

Out of curiosity in case I decide to purchase one of these antennas when they are available, I decided to calculate the exact USPS Priority Mail 2-Day shipping charge for this antenna. I used the exact weight (6 lbs.) and package dimensions (52" long x 6" wide x 5" tall) that were posted at RR.

I got a price quote from the 44431 shipping/manufacturing zip code in Leetonia, Ohio to my Fall River, MA zip code 02720 in southeastern Massachusetts. To my surprise the shipping charge for USPS Priority Mail 2-Day for all of those parameters was $12.80. YMMV based on exactly where you are having the antenna shipped.

I didn't even think of ice loading. What would the math be like for a fully coated antenna in a 30 mph sustained wind?

While I appreciate the effort that the new manufacturer is putting into this, I have to think that TV antennas, which is essentially what the ST-2 was, are made of lighter aluminum for a reason.

I'll be sticking with my Tram discone, although I am going to replace the RG59 with RG6 come spring.

I'd recheck the math, that seems very low. I know that I have sent a letter Priority Mail and it cost $7.50. A medium flat rate box is $16.00 something. Then again USPS rates are sometimes very odd. I've had cases where the cost difference between using their packaging and my own was a couple of dollars, but my package would get there at the same time.

Below is a screenshot from the USPS website showing the $12.80 charge for 6 lbs. (with the dimensions posted above) from the 44431 zip code to my zip code 02720. Note that the Priority Mail Express 2-Day has the same 2-Day delivery as the standard Priority Mail 2-Day but the price is $40 higher!
