Perfect HOA friendly antenna, discrete and stealthy Broadband Butterfly Terminated Dipole
***As of 10/18/2018-the business linked below (where I purchased the resistor and balun) is no longer operating***
Need a hidden, stealthy, HOA friendly antenna? Then this might be for you.
I decided to try a Broadband Butterfly Terminated Dipole (BBTD) and this is the installation. Testing on the RBN I used an Icom IC-703 at 10W.
The 16:1 Current BALUN with Quad, ferrite cores used to feed, (T2FD)
800 ohm terminated, folded (squashed Rhombic) dipoles and 1200 ohm Broadband Termination (Non-Inductive) Resistor
came from this site:
It appears the store is up for sale..hurry for some deals

http://hflink.com/antenna/Broadband Butterfly Terminated Dipole Antenna BBTD House Roof Version
The BBTD Antenna House Roof version can be utilized with buildings of various shapes and sizes. As a guideline, the more wire around the perimeter, the better the performance will be at lower frequencies (below 6 MHz). The length of wire on each side of the balun to the resistor should be within about 6ft (2m) of the same length, to maintain good SWR and balance of the antenna. Use insulated wire; #18 AWG (1mm) insulated wire is sufficient size for 500 Watts transmitter power. #22 AWG wire is sufficient for 100 Watts. The wire may be formed into a zig-zag, serpentine pattern, bent up and down, or around the corners and crevices of the building. It is very advantageous to elevate the wire as much as possible. The balun and/or termination resistor may be mounted inside the building, and the wires routed through air vents, gable vents, or holes in the walls or eaves. The insulated wire may be placed under or over eaves, or in gutters, or in the attic. Avoid close proximity of the balun or the resistor to AC mains power cables, because of risk and RFI or EMI or RX noise. Do not let any antenna wire touch an AC mains wire, internal or external to the building. Warning: contact with AC mains can kill you. Also, be sure to use good lightning protection.
