Greetings!
[Bruno - keep the Cannoli - leave their radio set to Channel 6]
Keep the radio, but use a different antenna - Crossbows are fiberglass sheathed - hollow, sign - board wrapped in plastic - sheathing, housing an aluminum Shower Curtain Rod material using a torodial core balun that is similar is size to those found in switching power supplies.
It's not waterproof, and you may see a tiny drain hole in the bottom by the coax SO-239
You can do better with a 18' piece of Coax and a dummy load soldered onto the end of it.
The 810e is great little radio - and even if they only told you Buy This Radio for $40 and well give you an antenna for free...
The above sounds better - and DONT USE THE CROSSBOW on a good little radio like that, else the Uniden Gremlins will rise up out the earth and pummel you with it...
On a lighter note ... DON"T USE THE CROSSBOW on that radio - get rid of that antenna - that Cobbled-copied JB1 - Big Stik wannab'e - it is not worth the hassle, heartbreak and frustration you'll get by trying to install, use or otherwise operate the system using that A99 throwaway look-alike...
(Handy Andy - settle down ok? - ed.)
Ok, just use a good antenna - just not the Crossbow - you'll see that I mean when you experience a long night of rain or a foggy night with a high dewpoint - you'll be waiting for DAYS for the antenna to drain out and dry out the electronics so you can talk to your friends without destroying the finals due to the high SWR from the water that pooled - filled that moisture-attracting, water-affinity-based, fiberglass-sheathed, 2-piece, Closet-Rod of an antenna the thing really is.
It comes from personal experience - and no, you can't run power thru it - see above - it uses a Balun and it's power dissipation is minimal and will scorch the antennas' outer fiberglass sheath from it's heat.
I used to sell those crossbows - and handled a lot of returns - much of them due to the blown baluns and cracked bases from the toroid disintegrating inside due to the heating effects from the power of an amp roasting them...<50W power rating...
Due to R-Shacks return policy at that time I was employed thru them - we ate the cost of a lot of those until the boss said enough and we simply said we're outta' them - they went elsewhere - but we never truly recovered from that mess...
Use the Crossbow for what it is, a 2-piece Closet rod - or remove the upper flexible whip section and it's backwards threaded coupling and convert the lower section into a bird-house holder for your backyard...
Don't try to use that antenna as a means to save lives, or prevent disasters - because it already is one...unable to save itself from itself...
All the best!
Hope the 810e works out well for you!
Regards!
