I had teh radio shack discone antenna which worked well; but during a recent storm, we had higher than normal winds and... all (8) of the long rods broke off and 4 of the shorts broke.
I tried using solder to get them back up but it didn't last the 1st cold night and a bump made them slip apart.

I *finally* got thru to someone at a local radio shack that was at least willing to look up the part numbers... ready ? $8.69 for 1 of the long rods. That would be more than I spent on the antenna itself. And they didn't carry one ("Who uses scanners anymore, it's all encrypted anyway") so I left a bit annoyed.

I have a nice whip type on my truck; works but not as well as the discone, especially at our new location. While unpacking I found a "motorola signal booster" (likely purchased to see if we could improve on the over-the-air digitial tv). The unit was never opened. Says it will boost 52-1000mhz -- close to full range coverage; work trying it along with the truck antenna as a base? Will the "out of boost range" signals (ie: 1200mhz) be passed thru w/o boost, or lost?

Here's a link to the booster: Amazon.com: Motorola Signal Booster 484095-001-00 Bi-Directional RF Amplifier (Discontinued by Manufacturer): Electronics

I thought about getting some all-thread as a replacement, but they are $5/piece so not exactly 'cheap' fix.

Anyone have any other repair ideas?
Has anyone tried/used ST4 Antennacraft?

There are other places to get DISCONE antennas which are better construction than the hollow tubed RS type. Diamond I believe makes one try looking on scanner master.

I had a radio shack discone (gave it away) tried a better quality discone but I never really liked any of them.

I got fed up with the cheap crimp on threaded sections on one of my RS Discones and replaced all elements with 3/16" aluminum rod. I bought the rods in about 10ft sections for less than $3 a rod. I threaded the rods with a 10-32 or maybe 10-24, I forget, then threaded the existing holes in the hub to match. Works great and its been up for about 10yrs now.

Do yourself a favor and get a better made discone. Those hollow rods with the crimped on ends is not a good design. Several folks have discones with solid rods that won't break off when a fly buzzes by and if you look around, many are sold for much less than the RS version (several years ago I got a T-601 new at a hamfest for just over $30, tax included). Links to some are below (note some have the top whip specifically for the VHF-Low band like the RS model while others don't so verify this if VHF-Low coverage is important to you).

Until an ice storm finally finished off my old RS discone, I kept it up and used it although it only had 1 long rod and 2 of the short ones remaining on it. The rest of the rods and the VHF-Low whip had long since dropped off. It still worked fine for the many strong signals here so I figured I'd keep it around.
