[Boatanchors] Off Topic Antenna Question

[Duane Fischer, W8DBF]

Hi Bill,

Not a commercial endorsement -

IAC (International Antenna Corp.) makes a very efficient and darn hard to 
spot multiple band antenna. Check it out on their IAC web site Bill.

I have used three of their mono band double bazooka antennas with excellent 
results. Their products are somewhat more expensive then comparable brands, 
but IAC pays a lot of attention to excellent workmanship and quality 
components. I have found their products very difficult to beat.

Check out their offerings for a multiple band stealth antenna OM.
