Abstract:

This article describes the design and simulation of a Comrod AH-52 HF/VHF broadband dipole, using the software MMANA-GAL. The simulations does not include the loads and thus are focused to obtain the approximate radiation patterns of the antenna in several frequencies in the HF band.

Warning: provisional model in process of modification. The results may be inexact or even contain errors.

	Type: Inverted V dipole
	Design: Comrod Communications Group
	Impedance: 50 ohm
Simulation: MMANA-GAL	Band: 2 - 88 MHz
Remarks: Loads not simulated.

1. Design and antenna modeling.

Fig.1. Comrod AH52 antenna model in MMANA-GAL.

The COMROD AH-52 is a broadband inverted vee dipole with 25-meter arms and one load at each end, suitable for ALE operation.

2. Radiation patterns.

This section shows the results of the simulation of the antenna with MMANA-GAL, in what concerns the radiation patterns at several frequencies of interest.

Fig.2. Radiation patterns at 2, 4, 6, 8 and 10 MHz.

Fig.3. Radiation patterns at 11, 13.25, 15.5, 17.75 and 20 MHz.

Omnidirectional behaviour and suitable for NVIS up to 10 MHz, with 7,5 dBi of maximum gain. Cardioids at 8 MHz. Suitable for DX at frequencies higher than 10 MHz, patterns strongly frequency-dependant.
