Oct 15, 2020 · There is a site that caters to 6m repeaters and a favorite 6m base antenna is the KRECO folded coaxial and they mention its got enough band width to easily cover the transmit/receive spacing where the non folded whip version does not, showing the folded monopole has a greater band width due partially due to more metal hanging out there.
Architectural MonopolesConcealed Solutions Lampshade structures Multi sided monopole platform based solutions With over 28 years of wireless communications experience, Valmont Larson is the industry Antennas and radios are easily accessible similar to standard monopoles via safety climb
This is post 2547 in a continuing series of simple ham radio antennas. Thanks to Lucien (DH7LM) for this exceptionally well-presented tutorial on one of the best HF antennas available to radio amateurs--the monoband HF dipole. This antenna is simple, inexpensive, and suitable for both at home operation and in "field" activities.

Concealed CFRP Vehicle Chassis Antenna Cavity - IEEE Dec 08, 2016 · Abstract:A concealed vehicular carbon fiber reinforced polymer cavity in the roof that contains antennas is proposed, prototyped, and measured. Compared to state-of-the-art roof-mounted shark-fin modules, this offers significantly more room for antennas and radio frequency hardware, thus enabling a smooth transition of vehicular connectivity towards 5G.
Dipole and Monopole Antennas - Radio EngineeringAug 23, 2020 · Dipole and monopole antennas are omnidirectional in the plane perpendicular to the wire and thus have a low directivity. Figure 9.13 shows a Yagi (or Yagi-Uda) antenna, which is an antenna commonly used for TV reception. It consists of an array of parallel dipoles, which together form a directional antenna.
The first is a planar inverted-F antenna that can be concealed in the bumpers, the second a hybrid structure based on the top-loaded monopole principle and mounted beneath the vehicle's roof

The Pros and Cons of Monopole Antennas - HubPagesNov 21, 2019 · The Advantages of Monopole Antennas . As the monopole antenna gets longer and the ground losses are reduced, the efficiency of the antenna gets better. Vertical monopole antennas can achieve efficiencies of up to 80%. A vertical monopole antenna can be used for any frequency shorter than two thirds of the wavelength.
A means for concealing an antenna within an extension of a common roof structure using an electrically shortened element laminated between two layers of non-RF conductive material which add to the strength of the invention as well as concealability. The antenna itself comprises a vertical radiator and a helical counterpoise of metal strip, wire, or deposited metal fed at the center point.
